Not official but here are some 100% crops of straight from NEF
JPEGS, taken using an allegedly production D200 converted using
faststone image viewer (not even the best converter on the market),
no other processing done to image.
[ISO 3200!]

[ISO 1600!]

[ISO 800!]

Those look as good as or better than shots I've seen in similar
light level taken with the 20D..and look, all the detail is
preserved even at ISO 3200! The slight chroma noise that is visible
at 1600 and 3200 can be blanked out with Photoshop's noise removal
filter without affecting detail at all.
It is pointless to compare at lower ISO since they are all clean
from highlight to deep shadow when processed from NEF. And these
images were slightly underexposed! Only question for me is how
close will the best possible out of camera JPEG get to this? The
original NEF's used and jpegs (shot with NR applied) can be found
here:

There is no longer a question of excellence for the image quality
at high ISO for the D200.
