That's one of the things I've been wondering about. Everyone seems to have been assuming that the AF would be identical to the D3, but that's not necessarily the case. After all, the D300 has the CAM3500 (DX) AF system but is reportedly slower than the D3.

One quick test doesn't fully answer the question, but I find this report interesting.
