I have tried the Heavy Rain demo with the Move, it took me several tries to get the movements correct. They are extremely specific, you can't just wave the controller in the air and get it right.
I agree with Reasonable's comment, though still adding Move support would be good for the gamers that want it. They wouldn't be cheating gamers at all, this is an FPS game and people love to use a motion controller for FPS games. Although I probably wouldn't use the Move if they added support, but I do think it would fit the style.
