Amazon is dropping the DB900 daily; down to $466 today with free shipping (Cameta seller).
The D700 will probably drop dramatically after Canon brings out its 5D replacement.I'd guess $2,000 by early next year is not out of the question. $3K is still a lot of money and most pros who really needed full frame went to Canon three years ago. The few pros who stayed with Nikon and really needed full frame bit for the D3. That leaves mostly bleeding-edge amateurs to buy this camera, and money isn't is as easy to come by this year as it was last.
