Well, DxO seems more objective than pure subjective evaluation.
Thanks for the link!
Comparing colors under different WB or exposure is difficult. The D700 picture is slightly darker than the D7000 picture. Take any picture if turning it brighter or darker, you will notice the color differences.
You mentioned DR, which is directly related to noise performance. It's not possible to have a sensor that is noisier but with better DR. From the pictures in the link, to my eye, D700 is noticeably better at ISO 400.
Don't know what the "experts" will say once they finished the reviews. So far, I tend to think it's not a sensor with revolutionary ISO performance.
