The autofocus system was on of my main points previously posted. The D7000 has a brand new system. The replacement for the D700/D3(x) will not be the same autofocus system in my opinion. This means Nikon already (likely) has two brand new systems (at least in development, if not already finalized). Is the D300s replacement more likely to share the same auto-focus system as the D7000 or a higher-end model? If history is precidence, the D300s replacement will have a different, new autofocus module not yet released and not shared by the D7000. Obviously mere speculation at this point.
