Attached is the 100% crop (from a 100-400mm L). And the second one of the kingfisher for not being sharp enough. When I say picky, I mean picky. Your bird pic from the 1D X is far too soft.

My primary interest is wildlife photography and most of the shooting that I do is hand held because I do a lot of hiking with my camera in rough country.  I recently acquired a 7D and the EF-L 100-400 to replace my T3i and a Sigma 150-500 lens.  I am astounded by the improvement in sharpness that I'm getting.  Photos at any ISO are far crisper with my 7D 100-400 package than with the T3i/Sigma combination taken at the same ISO. 

My point is that I couldn't imagine that there would be that much improvement over what I'm getting with the 7D in a full frame body.  There comes a point, and I believe that I've reached it, where my eyes are simply not good enough to tell the difference.

Yeah, it's front-focused a bit, for one thing, and needed a deeper DoF - but it was overcast and near sunset, and I was already at f/4 and ISO 6400...

Since the T3i and the 7D have the same sensor, the effect you are seing is due to the change in lenses.
The 100-400mm is much sharper than the Sigma 150-500 especialy  at the long end.
I think that you will see a similar change  if you upgrade  to  FF.  particularly at ISO 800 and above, where noise impacts the sharpness of the photo.
Look at Neuro's Cardinal at ISO 6400, this is what I would expect to see from a 7D at around ISO 1600

It is good enough to see the little fisher has been tagged with a leg ring :)

On my 5D+85/1.8 the image gets sharper going from f/11 to f/13 while I just won't go over f/8 on my XTi.

This was rejected for being too noisy.

Really? No one got the noisy bird joke but me? Buncha scientists and engineers not photographers!

So, if the 7D is capable of extrordinary resolution in perfect circumstances, does this also mean that the rumored high MP count FF camera(s) will also require perfect circumstances? Will cries of "soft" be heard when/if the rumored high MP camera hits store shelves in the near/not so near future?

Maybe the excellent high ISO performance of the 1DX is being "field tested" for the "1DXs"...
