Testing APS-C cameras at F/8 introduces loss in sharpness due to diffraction, and biases the results in favor of FF cameras. Even imaging-resource.com does this...
I understand that from a techinical standpoint diffraction causes some degree of IQ degradation on 1.6X crop, but I highly dout that you could see the effect of diffraction at f/8 vs f/4, even looking at 100% crops.
If this is really true, then someone show me crops at f/4 and f/8 with the 7D that shows that the f/8 crops are worse.

The 5D is the closest thing to what you are looking for. If you want a better AF system you will also have to settle for HD video - as that is going to be a standard feature on all DSLRs under $3,000 whether you like/want it or not. I myself couldn't care less about the video, but I want a FF and also a good AF system. If the 5D's AF falls short of your needs, wait for the 5D Mk III - it's guaranteed to have at least 19 cross-type focussing points.

I hope your right, but I'll believe it when I see it. I don't think many would have predicted that the 5dII woud not have had at least a partially upgraded AF.
