Official statement from Nikon on the image quality of the D4 vs the D3s

According to Nikon the image quality of the D4 and the D3s at high ISO is the very similar but with more detail in the images of the D4 .

Here is a portion of an interview reported at

"Q. How would you compare the high ISO image quality of the D4 to the D3S?

Overall, D4 high ISO noise levels are very similar to the D3S, though photos shot with the D4 will have reduced colour noise (thanks mainly to noise reduction improvements in the D4's EXPEED 3 processing hardware). The main difference you'll see in pictures from the two cameras at high sensitivities is in the fine detail: D4 photos are noticeably better in this way.

(Akagi then showed several 13 x 19-inch prints of the same scene , captured as NEFs with the D3S and D4 at ISO 12,800, in which the overall colour, tonality, visibility of noise and shadow rendering couldn't have been more similar . But, the D4 photos looked sharper and more detailed . The D4's crispness advantage in Nikon's comparisons was significant , suggesting that we were seeing the effect of more than just the new camera's higher pixel count.)

Q. Among the image quality improvements cited for the D4 is better skin tones . What difference would we notice in a portrait shot with the D3S and then the D4?

You will notice better tonality . We have reshaped the tone curve to give more natural-looking shadows and shadow transitions in faces.

(This change presumably will be apparent in photos processed to JPEG and TIFF in the camera, as well as NEFs converted to finished files in Capture NX2.)"

Conclusion: If this statement is true the final images shot with a D4 at any high ISO setting will be superior over the ones from a D3s because the files from the D4 will tolerate more NR and sharpening.
