I just got mine today and found out that it only holds 1 Nikon battery instead of the 2 my D80 grip held. Not a real problem.
Can you have a battery in the camera and in the grip simultaneously? Would the camera use up the one in the camera first and then use the one in the grip. I'm assuming not since there is no mention in the MB-D11 instructions about leaving a battery in the camera.
Did some more searching on the web and found out you can use a battery in the camera and in the grip at the same time. Have not yet discovered if both are used at the same time or if they switch when one gets low.
If you have batteries in the camera and in the grip, they are used in sequence, not both at once. I believe it's possible to specify which of them gets used first in the camera menu. When the first one gets too low, the camera automatically switches to the other.
I have the MB-D10 attached to my D700. The order of the batteries is grip first, camera second. When the battery in the grip gets low I take it out and charge it. On the rare occasions that it runs out whilst out using it, the camera uses the switches to the second battery. However because I will charge the grip battery at the first opportunity and the camera then switches back to using it, the battery inside the camera only needs charging every 6-8 months.
Plus, you can select which one gets used first (presumably the one in the grip). It's in the owner's manual. I don't have my D7000 yet, but I downloaded the manual from Nikon, and have been reading in advance.
The old grip with 2 batteries, as on the D80, is nice, but it's kind of an ordeal to remove it, replace the battery door, etc. So I tended to leave it on all the time. This newer system seems to be a lot more flexible. Only once have I used the second battery, during a one-day shoot of 1,200 images.

I prefer the setup you describe and it is used in the D300/700. Yes, you can set it to use the MB-D11 first, then the in-camera battery. It means that you can have easy access to the D11 battery for re-charging, However, I have marked the batteries 1 & 2 and every now and then I swop them around as batteries have a longer life if you cycle them.
I don't believe that there has been any other aftermarket battery which has increased the frame rate for the previos version. A set of NiMh batteries in the grip would do that. I would not play with the aftermarket stuf anyway - remote shutter release - ok, grip from a different vendor - ok as well, but anything that would supply the camera with a higher level or an unreliable level of "juice" - I would stay away from that stuff - risk of possible leakage or damage. I may be wrong, but i have 3 Nikon batteries of the previous generation for 4 years now - and they still show as new in the battery menu of my D300 and D700.
Cheers, Kevin >I am wondering if there will be an aftermarket 2 battery unit >made which also gives us a greater frame rate?
I don't doubt that an aftermarket battery or a set of them in the add-on grip could increase camera performance. When I added a large acid battery to my Kodak DC760, that camera literally came to life. It not only increased the frame rate but also speeded the focusing. If you can get a hold of the data, you will find due to the nature of any battery a camera will operate at a fairly wide range of power level.
I have used plenty of them successfully, but plan on using Nikon batteries because of all the proprietary information required by the camera. For my use the Nikon batteries are also relatively cheap at $60.
My questions have to do with the aftermarket Grips. 1. Do you think they will come out with one that holds two EN-EL 15 batteries or one EN-EL 4a (D3) battery? 2. Would this provide more performance or just more battery life?
From what I've seen, it will just add more battery. I have the MB-D10 for my D700 - and this just adds more battery - now, if you stick an EN-el4a (a $105 battery from Nikon) into the grip - it provides the same frame rate as the NiMH batteries - this brings it up by 1.5-2 fps, I think.
Picked up my D7k a few days ago. Yes, it has a place on the grip to put the rubber cover. What it doesn't have is a place to put the white plastic cover that goes over the connector slot on the grip. Maybe that piece is just for shipping, but I plan to use when the grip is not in use. Also, as mentioned, this grip is easier to remove and replace, so I'll probably be taking it off occasionally. On my D80, I leave it on all the time.
There is a setting to use the grip's battery first. As suggested, it's probably a good idea to rotate the batteries to even out usage. The grip was $269 and the battery $72, at my pro shop.
