Nikon AF improvement?

However, I've been reading Thom's latest post, which in turn is sort of a follow up on a recent discussion on this forum, and the constant controversy over whether D800 is a D700 successor. Thom's argument is that shooting sports timing and anticipation matter more than the burst rate. In principle I would definitely buy this argument. I shoot sports quite a lot, and I don't routinely use large bursts, trying to better anticipate things instead. I still can't quite wrap my head around the fact that you can shoot sports with a camera that generates a 70MB raw file per shot, and that it makes any sense for this application. But this aside (and it is a big psychological barrier for me), the usability of D800 for many types of photography I can relate to boils down to its AF module.
