I can say ME 2 and Gears 2 are definitely possible as they are UE 3.5 games
The others, well it is impossible to really tell, but they certainly could not be ported directly. Certainly Uncharted 2 is designed around the PS3, so that the SPUs are in use 100% of the time.
Oh, and GoW and Uncharted are brand names owned by Sony, so they can't go to the 360 to answer the title question
