I agree with several who say the photographer and subject play far more critical roles than the camera. I have a large number of superb and memorable images from my months in Baghdad immediately after the second Gulf War -- shot with a D1X. I have still more images in my files that I shot with my D100, and a large part of my web site derives from images shot with a D200. I have not moved any of my D800 shots to my site yet. And none of the images I have cited deteriorated when I got each new camera! I still have my Dad's Nikon S -- the other cameras (F, FE, FE2, F3, etc.) seem to come, stay awhile and then go away. But the photos and memories last forever. While I update -- I'm awaiting a second D800 right now -- I do so because I enjoy the experience with the new tools. But the old cameras served me pretty darned well too. And oh -- let's not forget lenses. My entire D700 kit is moving along to my D800 bodies as I sell the D700s.
