I'm trying to gauge an upcoming vacation that will be soon after I (hopefully) receive the D7000. I hope to get a good amount of 1080p video. I've searched all over, including the reviews, and maybe I'm overlooking something, but can't find the average 1080p file size.
I guess my question is, if the maximum is 20 minutes, if I max out the settings (1080p) then what will a 20 minute video file weigh in at?

Not sure of the answer but 1080p using the compression system in the d7000(H.264 and MEPG-4) you would be able to get 20 minutes on a 2 gig card, or more. It depends on how aggressive they have it set for.
I am confused by the need for 20 minutes. If this is vacation time, who is going to sit through 20 minute scenes without a break or cut? Who is going to other editing such long scenes? Recording a ball game or movie might require long takes but those already have intense scene cutting. Few people can sit though any scene longer than 1 minute without a change in perspective or scene. The 5 minute scene limit of the D90 was complained about by most people but not at all by people who knew how to shoot videos. Take any TV program, movie or commercial and try to find a scene take longer than 1 minute.
It will be a monstrous job to edit a long continuous scene into a useful video. Better would be to take longs of smaller files, each well id'ed so assembly editing can be easier and more interesting.
I see tourists every day who keep their camcorder to their eye for hours, filling a tape or large card. No one is every going to watch that, it is a waste of time and keeps that person isolated from the the location they came to enjoy. Take a series of related scenes, each with multiple takes if you want anyone to watch it.
Good videos are much harder to take than good stills, or else there were be more of good videos and sadly there are only few people with the talent, technical skill and creativity to plan out and execute a watchable video.

Thank you for the response. The only time I could see myself needing to shoot continuous video longer than a few minutes could be a speech or something that I really needed to capture. A while back I had been asked to capture the vows during a really small wedding ceremony. I borrowed my friend's D90 and had to shoot a bunch of different files, because they rambled on forever.
I was mostly interested in knowing what the maximum size was so that I could decide if I really need a couple 64gb cards. They are ridiculously overpriced so I'd rather stick to a bunch of 8 or 16gb cards so I can swap them out and not shoot all my pictures and scenes on one card.

There are a lot of reasons to need more than 20 minutes. When you are doing a multi camera shoot of a live event is just one that I have done many times. Without the ability to sync to a common sync clock, you need to run multiple cameras continuously for much easier syncing later in post. One live event where the need for more than 20 minutes is pretty strong is for wedding video, even for single camera shoots. I have yet to see any wedding videographers shoot a ceremony with a 7D or 5DmII at my weddings yet, although I am sure some are.
It will be a monstrous job to edit a long continuous scene into a useful video.
This is absolutely NOT the case in my opinion. It totally depends on your editing style. For me, I prefer to bring in all of my clips in the timeline consecutively, regardless if I have a lot of clips or just one. Unless I am chopping out a lot of unnecessary time whilst shooting, it is easier for me to chop out and make fine edits in the timeline in post. Other editors have differing styles and preferences. And much depends on what you are shooting and what your final production is intended to be.

The OP asked in regard to an upcoming vacation. That makes a big difference, few people take a second unit along on a vacation. Normally scenes are of difference subjects related only in that they are from the same vacation. Separate clips, properly logged will make editing much easier. My gripe about DSLR as a video production tool is that it is the wrong tool for the job because of what you mentioned, lack of standard reference signal sync so every source is running wild. Normally a master time code clock would run continuously to which all else is sync'd, not individual sources. Still camera people usually do not think in terms of systems; sound sync, color and frame clocks etc so shoot without thinking of the most important task of assembly. Post houses hate seeing that sort of job walk in the door because DSLR makes everything downstream more difficult and compromised.
All this will be a distant memory in a year or so when the fad abruptly ends when some camera manufacturers put large sensors in video plan-form cases with all the proper reference interfaces for not much more than a good DSLR now. 10 years from now few people will even remember that marketing departments, instead of engineers, tried this little short lived experiment.

I am not so sure about this being a fad. Apparently studios have been using the 5dM2's as throw away cameras for tricky stunts in large budget productions. 5D2 footage also showing up on in several prime-time (US) network broadcasts as well. The quality is plenty good enough for 1080i/720p netowrk and its also good enough for film-makers to splice 5D footage into their movies. The cost is so inexpensive that even if it gets destroyed it does not break the budget. It has a similar look to cameras costing 50 times more expensive and much larger. Studios are actually buying these cameras now some numbers to shoot video. Its not just marketing. The cameras have some use. But 10 years from now, we might be forgetting about a lot of useful tools besides video coming out of a still camera form factor. This should not diminish the the usefulness right now of shooting video with a D-SLR.
For amateur / family / vacation videos, consumers are looking for convergence. Just look at the i-phone, as one huge example of convergence. Consumers who want both high res stills and good video may think that a video enabled D-SLR is a good choice for them. For these folks, I would agree that 20 minutes is fine for the clip limit. I agree that the D-SLR form factor and other features are not all ideal for video. But look how many people are shooting video on their cell phones now and it is popping up everywhere. Consumers are no longer buying video form factor camcorders in any numbers. While they are willing to "lug" around a D-SLR (for now), they are not willing to also make room for a camcorder. Therefore, it just makes sense to be adding video to the D-SLR. I have no concrete guesses for what consumers will want in another 10 years. But for now, it is a meaningful feature for many and is not just marketing hype.

The specs for the D7000 are here:
The specs indicate a largest file size of
1,920 × 1,080 (24p); 24 fps
Sound and other EXIF data would be in addition to the image file size.
The video compression standard being used is H.264/MPEG-4. I can't tell you what level of compression is applied, but would expect it is 15 times or more.
In the older cameras that had video, a card was filled up rather quickly.
With that in mind, I woudl expect a 16 GB class 10 card to be needed if you intend to shoot much video.

Disclaimer - I am a rank *video* amateur, so don't beat me too badly if my rules of thumb are way off.
General video file size rule -
Filesize = Bitrate x Running Time
Now, some postings at other forums indicate that the D7000 is equipped with B-Frames @ 24Mbps in the H.264 encoding. The info was supposedly solicited from Nikon pre-sales support. Assuming that's true, then 24MBps = 3MB/sec. 20 minutes of video is 1200 seconds:
3MB /sec x 1200 seconds = 3600 MB
divided by 1024 MB gives you a clip size of just over 3.5 GB, so you can theoretically store four full 20 minute segments on a 16GB SDHC card.
Edited to add: You can always ask Nikon Tech support as well. Just add the info above so that they know you're not asking a general question and they'll likely correct you on any tech specs. Build a Profile on the Nikon KnowledgeBase then use the "Ask A Question" tab.

Thanks, Sounds a lot better than my current camcorder and fighting with Mini-DV tapes

Yeah, absolutely. Going tapeless was the best move I've made. I keep one HDV camera around just in case, but it hasn't seen the light of day recently.
Rule of thumb for me is around 20 minutes on an 8GB, 40 minutes for 16GB, at 1080p24.
Which is plenty for a film (movie) camera. Not so great for a video camera. (see my long posts elsewhere in this video forum)
I'm being conservative, I know, but I tend to shoot a lot of stills as well as video - in fact, I tend to shoot the shot I'm going to do on video on stills first - kinda like the old school Polaroids we used to do prior to final exposures.
Just as a final check for focus, composition, props and costumes, hair, background garbage, light stands and cables, you know, the idiot check. Pass that image through to the video village via HDMI as a "last looks" so they see what they're getting - since when shooting the HD feed becomes a 480 SD feed and people start to panic.
Bear in mind card copying times, though.
For a commercial (paid gig) shoot it would probably be better using more mid-sized (16 or 32GB) cards than less 64-and-above GB cards totaling the same memory capacity, simply for the data transfer times: copying off a card into an HDD runs at about a minute a gig - so you don't want your cards tied up for half and hour at a time if they're 32GBs. 10-15 minutes usually isn't a big deal on set.
