Dpreview has posted their detailled Nikon D3X review:

“If you can afford the D3X, you will buy yourself the best image detail that’s currently on the market and a very versatile photographic tools. We’ve used it in the studio and on location, for portraits and for sports, in daylight and in dim clubs and and on every occasion we were amazed how easy it was to achieve good results with the camera. Therefore, despite its eye-watering price tag, the Nikon D3X without a shadow of doubt earns itself our highest award.”
