I am afraid they did the same as with the 5D2/3.
Basically as many MP, basically same sensor tech, but new processor and maybe stronger AA filter to get better high-iso and video performance.
You seem to have conveniently forgot the new
63 zone dual-layer metering sensor, new
61-point high density reticular autofocus, including up to 41 cross-type AF points and 5 dual diagonal AF points, , new
in-built HDR, new
dual slots for CF and SD cards (just to name a few) ... well I suppose when one does not want to accept facts it is hard to see
let's see if this camera looks better than the D7100.
I've used EOS 60D & EOS 7D for over 3 years (sold them to upgrade to 5D MK III and some L glass), I currently own a Nikon D7000 ... D7000 is a camera that fills the gap between 60D and 7D i.e. a little better than 60D and not as good as 7D ... the same applies to D7100 i.e. it will fill the gap between EOS 70D & EOS 7D II
