Apparently the new camera will be designated D80, this designation has been buzzing around for a few days but I have now found some photos (assuming they are not fake!)

It looks like it has an SD memory card hatch to the side. It would be an ideal second body for my D2X if it used CF but then I am sure Nikon would rather me buy a D200 as a second body that used CF.
