Removing the AA filter gets you, at best, 30% more equivalent pixel count, but it means you can't trust your images to show what was actually there, and it means you might get some very, very ugly and false artifacts that are obvious at any scale.

This was argued extensively when the D800 and D800E came out.  There was lots of angst among early adopters about which way to go, but now that people have actually used these cameras the consensus is overwhelmingly in favor of the D800E with no AA filter because its files are just cleaner and show more resolution at wider apertures.

Nikon has seen this play out and that's why you can't get a D7100 with an AA filter -- period.  Likewise Sony has done the same with their A7r.  As sensor resolution increases this is going to be a completely moot discussion and all cameras will no longer have AA filters.
