Well, go for the PS3, of course.
I mean, i'm not a big fan of PC gaming so i'm not touching it...
No reason to buy more games since you got this much of games to entertain you for a long time, and even longer if you are an achievement whore like me lol (trophy whore in my case)
Therefore, i'd buy a PS3, it' an awesome console.
