I looked at D700 sales on our sell forum from the past 6 weeks or so, and all 6 sales were right around $1800.
Maybe the D700 will hang around a while yet in the lineup. Nikon has been known to do this. Heck, the D90 is still available new today at B&H, even though production ended one year ago. The F3 outlived its replacement, the F4, and overlapped the F5, being made for over 20 years!
