The larger sensor (38x50mm?) has pixels almost twice as big (in area) and should have better signal to noise performance than 1 DS2, and that will put 645d in different league and command a higher price. That is, if Kodak does its homework.
Otherwise, sadly the 35 mm full frame from Pentax is as likely as US signing the Kyoto agreement. Oh well, maybe the 20D viewfinder is not that bad? I should have another look...
