I hope they at least consider releasing it for PC. This game and Alan Wake are the two games that I've always wanted to play, but don't want to buy a console just to play it.
And if you want to play both those, you'll need to buy an xbox AND a ps3
EDIT: I don't know if they can really release Heavy Rain for PC without major rework though because the game was all quick-time events and made heavy use of the ps3 sixaxis controller, it's not just about pressing the right buttons, it used the motion sensing too
Somehow you steal my posts from my brain then put them here. Stop that.
