IMO, Heavy Rain was a lot more fun to play with Move than with the Sixaxis(with move there's no dumb hold L2 to walk).

What are the chances this will have Move support out of the box?

I think they would have said something about it by now if it was going to support the move, maybe they'll put it in after the fact like Heavy Rain did.

I think I read somewhere that they aren't providing move support for this game. Could change their mind later on but I'm thinking they just want to focus on releasing this game and then possibly move on to something new for the next generation consoles.
