D700, D800 or D4?

In the exact situation, except I'm definitely not looking at the D4, as i can't put that much money in a body. I've decided to (again) buy a gently used D700 without cancelling my B&H pre-order. When the D800 comes I'll decide then whether to resell the D700 and keep it or just sell the D800 on eBay for a profit.

FYI - Amazon seems to be continually getting the D700 in stock if you want a new one, and they're all over CL, ebay, forums for sale used.
