Look for sample comparison between D7000/D5100 and D7100. If anybody notices any real difference, other than what comes as a consequence of a difference in resolutions (16mpix vs 24mpix), he ain't a regular guy - he's a bloody Superman (X-ray eyes?)

...
Really?! Thing is, without even downloading anything I can discern a difference here...
Is it
significant? Is it
subtle? Who cares, I can see it. Is it because of the higher resolution sensor and not the lack of an anti-aliasing filter? I don't know, but I don't care either. What I do see is more information for me to work with, more pixels per bird, more light, and that's all going to allow me to pull the most out of my photograph - the rest is all up to me.
Now, if you want to talk about the anti-aliasing filter, stop comparing apples to oranges and look at the 800 vs. 800e, because there you truly have "all other things being equal". Now, I could let wonderful comparisons by folks known in the field do my job for me (
Nikon D800 vs D800E,
Nikon D800-D800E First Comparison), but since you chose the battlefield just take a look at this side-by-side of the 800 vs. 800e...
No Superman needed, and if you did there would have been an outcry ages ago. This ain't rocket science. But if you can't see it there, let me stick it in front of you. From the Luminous Landscape comparison here you have two 100% crops of the same image with no add'l sharpening.
D800
D800e
Just look at the edges of the text and the crispness (or lack of it) in the watermarks. If you cannot see the difference, then I'm sorry for you and would be happy to schedule an appointment for you at the optometrist.
Look, I get it, some folks are natural skeptics. And some folks do actual research. Do all cameras and photographers
need a camera without an anti-aliasing filter? Absolutely not!! In fact, it could be hell for a portrait photographer shooting men in synthetic golf shirts. Are cameras without them sharper? Without a doubt. If I were a landscape photographer would it make a difference in my selection of a new body? Hell yes.
