I'm excited about the 24mp sensor and no AA filter, but this leads me to ask: What about Sharpening? Without the AA filter, is sharpening irrelevant? If not, how should it be handled differently than with previous cameras? I set my D7000 at '6', finding Nikon was very conservative in the factory setting.
I only shoot RAW, convert in NX2 or Capture NX3...
I wonder whether Nikon has changed their in camera sharpening for these models without an AA filter, I suspect they have.
Also given that diffraction is going to set in fairly early, sharpening will be necessary to try and recover some of that lost appearance of sharpness. Finding the balance in shots to get the maximum detail/sharpness as between aperture and diffraction will be interesting.

The AA tends to mask what would otherwise be visible diffraction. In that way it is 'effected', but not directly, it is there, it just cannot be seen. Without the AA, the effects of diffraction will be visible earlier.
The effect of the AA of course results in the loss of visible sharpness so there is give and take.
Sharpening is definitely not irrelevant - you'll just want to do a bit less of it. I have a D800 and a D800e and my Lightroom/ACR settings for the D800e are about 15-20 points less on its intensity scale than the D800 for roughly equivalent results. That's a different scale than NX2's sharpening scale, but the point is that you'll want to sharpen a bit less with a D7100.
BTW, I'd try moving away from Picture Control sharpening to NX2's USM sharpening unless you're just making family photos or other snapshots. Picture Control sharpening is really coarse and cranking it up just produces nasty halos rather than getting you fine detail. USM definitely offers better control, and then you also have the option of sharpening selectively. The difference can be pretty profound.
Also, are you just doing one round of sharpening or following up with a second round for the output format and size?

Bill, thanks for bringing the subject up. I am also considering the D7100 and have some concerns over the AA filter.
I am probably one of the worst at PP . This is ooc Standard pic control with sharpening at +5, saturation at +1, hue at -1, adl auto, NR moved to "better". CNX2 That is why I call it a "Cartoon" Click for larger
This is ooc with pic control back to neutral, 0 sharp, sat. and hue zeroed out and adl still at auto, NR left as is ooc. No PP! Anyone is welcome to play with it
Most here can make it look better and particularly Rick! I wonder what the rumoured CNX3 will look like ?
I do shoot a lot of sport in jpeg and nef and the kids do not mind the "cartoon' look at saves me a heck of a lot of PP

Here you go. This is a 100% crop of a small section of a shot made with a D800e. The first is sharpened via ACR 7, but I could have replicated its look using USM. The second is with a Picture Control sharpening setting of "6" in NX2.
I have a pretty strong preference for the first shot.
For most people using the PC on these forums, the use of PC sharpening is for in-field rear display evaluation and not actually using JPG for prints or presentation. I set a PC with +6 sharpening just for that purpose and from I see on the forum, that is typical. Sharpening in post on RAW files is best done selectively and appropriately for the output type. Usually as a multi-step process, once before re-sampling and one after. One of the features of NX2 I really like is being able to embed various versions of the same data in the single raw file so one can be for large print, another small print and yet another for screen viewing, all with different sharpening radius and amount, and contrast that fits the presentation characteristics. An image destined to be viewed on a Retina disply tablet will need different settings than one going to a inject printer for example. Stan St Petersburg Russia

The first is clearly better... I use a setting of '6' in the Camera, not in NX2. So the haloing on the branches in the second image is not something I've noticed. I've never had to use NX2 to lessen what the camera put in the RAW file. I also use Standard Mode.
I typically print 12x18 for ones to keep myself, and 20x30 on glossy aluminum for exhibition and sale. 99% of the time I'm printing completely uncropped images.
Typically, and I know this is bad, I PP for the largest size, and don't bother touching the sharpening (or anything) for smaller sizes. I print from the full file no matter how small the prints are going to be.
So, I suspect from all this that the setting for sharpening in a D7100 (in-camera) will be very low. Actually, staying apples to apples, I'd expect a bit of resolution increase to be noticeable at 20x30" even with no sharpening applied.

Here is an example that I set up. The jpeg is unaltered, it was set to maximum sharpening in the D3100. The RAW file was edited to add the Nikon Standard profile and sharpened with the LR4.3 dialogue. Otherwise, to keep all things the same, I left the RAW file alone.
I believe I can not only see no halo effect in the RAW, I actually see the fine texture of the box that in-camera processing smoothed out. Personally, I prefer the RAW.
If you're using NX2 to process your raw files, it doesn't matter where you set the sharpening level - it's the same. If you're shooting jpegs, the Picture Control sharpening level is a bit lower, but the same problem exists with a lack of fine detail in images.
Ultimately, it's up to you how you want to work with your images, but a lot of people don't know how good their current cameras are because of how they sharpen in post-processing.

Thanks for the info. I never shoot JPEG's, and my assumption has been that NX2 imported the RAW file (with camera settings in-tact, and also removeable). PP is my weakest aspect of photography, and I'm sure I'm only getting 25% of what NX2 can do. Mainly, I use it to touch up saturation, and, if needed, global sharpening.
I really work for getting what I want in-camera -- a habit from shooting slides.
Having said that, I'm coming away with extremely good detail without the "haloing" effect which I think I would have noticed.
The removal of the AA filter will almost certainly be accompanied by a change in how in camera sharpening effects images. In camera sharpening was largely meant to counter the effects of the AA filter. At wider apertures (before diffraction becomes a real issue), very little if anything, should be required (unless the image lacks sharpness for other reasons such as camera shake - but that is really a case for PP sharpening or better, taking the photo again and trying to eliminate the shake). As aperture increases and diffraction becomes visible it could assist in making the photo appear sharper, within reason.
I am actually really interested to see how Nikon deals with this.
I have seen some really sharp RAW files from the 800E with no sharpening applied. I expect the same will be true of the D7100, perhaps more so as the filter has been completely removed.
