however, it seems like Nikon gets better IQ out of their 1.5 crop than Canon did out of FF. So, crop apparently already caught up with older FF.
I wouldn't really cite a computer generated comparison as a reliable source :-o ... esp. I really doubt the advantage of the d7000 in dynamic range (at which iso???) because it seems you can recover more dr out of Canon raw files than from Nikon. The noise comparison doesn't say what iso they tested or how it was averaged, that could have given you some doubt...
The computer generated comparison uses DxO results as a basis for the analysis. Many people seem to consider DxO to be a reliable source. DR will most likely be done at ISO 100 and a better RAW file format doesn't replace a better sensor. Anyway, my point is that we'll definitely see an APS-C sensor in - let's say 5 years - that will have a much better performance than for example the 5D II.
Overall, I believe that a modern APS-C is already much better than an old FF (like for example the 5D) - and this development will keep on going.
