One thing that I noticed immediately is that the Canon colour-balance of tradition seems to be gone. 7D shows more of the "very neutral" D5000 character. It's at least as good the D5000, and the difference is actually bigger in lower ISO's - but that was to be expected.
Since all three Canon testshots showed obvious signs of (at least) chroma NR, I've applied some to the D5000 picture as well. I do recommend the 100% view, if you want to see any real change.
Minimal hue and saturation changes have been done globally to make the comparison easier.
