Thanks for looking into the topic. Nikon states the D800 is not the D700's replacement. They claim it is an entirely new class of camera. 2 more bodies are due this year. I expect one of them will be the missing D700 upgrade.
Also the D700 is still being manufactured only because of left over parts. It's withdrawal is imminent, we just don't know when. Natural disasters have meant a lot less of some model cameras were made in the last year than expected.
D800 gets a forum all to itself means cool factor +10.
