This would make complete sense if the D7000 was intended to occupy the position of the D90 in Nikon's food chain, but according to Nikon that is not the case, it is to seated higher up. Now of course this may be marketing mumbo jumbo to try and keep the D90 moving and sell the D7000 as 'semi-pro', but it is entirely possible that Nikon has put features in the D7000 that will be used in the 'pro' marketed cameras.
Nikon's AF system is already much better than Canon's imo, it is almost mind boggling to consider it getting even better. That would be fantastic. If they put it in a DX camera that would be equally fantastic as it would again show Nikon's commitment to DX. I still think that the D400 will have a version of the 4800dx, but this is also speculation.
