From memory, wasn't the D300 or D300s said to be using the "same AF" as the D3? I think I remember reports it was quite a different story in the field though. Nikonians will correct me.

AF & metering systems of 1D-X and 5D-III seem to be a different story though... AF modules could be more or less the same but 5D-III is not equipped with a 100K RGB sensor for metering, which helps AF system for moving objects. I think this should make a difference.
But all in all, as you and Popo already mentioned, I agree too that the AF and metering performance of 5D3 is clearly improved (at least on paper)...
