does any one know whether the game ‘i am alive’ is coming to xbox 360?

I’ve read around and i seem to be getting mixed answers some sites say it will be released on 360, ps3 and pc, others say its just the pc and ps3.
any one know which, if either are true????
I do not like those games. but I see that movie and I really will like to have that game. I have heard my brother saying the game is just in ps3
According to Gamespot, the game will be released on PS3 and Xbox 360 later this year.
