Take a look at the samples on the official nikon page. Is it just me? I am a little underwhelmed regarding image quality at display ...
Not only you.
I took a look at them. Downloaded them and made a couple of prints on the Canon ipf8000.
I also took a look at the histograms in some advanced color grading software.
I did not like what I saw. The did not look as good as D3x. Blacks and shadow detail not as good.
Skin tones are not particularly nice either.
The Canon 1D X on the other hand looks like a significant improvement for Canon. I think they really hit the sweet spot with the gap-less 18 MP sensor.
Black look far better.
