I had a D2X since March and used it almost everyday until last week when the "F" word happened. As the new D2Xs had come out I asked about upgrading to it even though I had ordered a D2X. When I got the D2Xs not much had really changed that would help the under water photographer, however one thing that had changed was the new TFT LCD screen.
The warning is that if you have used the D2X then upgrading to the D2Xs will leave you very disappointed, for one reason. The new TFT under water does not produce those nice blue backgrounds you are used to. Cathy Church photoshop (CC) here in Cayman and I have been working on the problem but it seems that the change in LCD has a strange effect under water. It shows a murky blue'ish instead of the deep rich blue I was used to. With help from CC we changed every setting the camera has, including adding a color curve into the camera from Nikon Capture, but the screen remains the same, a murky blue'ish color. The new Nikon D80 has the same screen and will no doubt have the same problem. The D200 DOES NOT have the same screen that you may have read about, we compared them and you can clearly see the difference. When you view the images on LCD's you can see the lack of blue. Sure you can add blue color curve in Photoshop but I'd rather do it in the camera like I have been doing. So to conclude I have asked them to exchange it back to a D2X that I know and like so well, I'd asked for it to be chnaged the very next day but they convinced me to try a few setting changes first but to no avail, I'll tell you how it goes on Monday.
I found this image of a nice area that I take photos of when ever I'm on that dive site, it was taken 2 weeks ago with the D2X. Settings are: RAW 80th, f-8 iso 100

Sorry for the edit, Luiz I used the wrong image, in the example, on the computer they look almost the same it's when viewed on the LCD they look different. We took a D2X and D2Xs underwater and took a photo of both screens side by side and in it you can see the differnce, but on the computer they are alomst the same.
