You wanna be sure about that, because GTA started out on the PC and then was ported to consoles. And who cares if XBL went down for 2 hours, because I didn't even notice. And before you go on about the 360's RROD, let me remind you that the PS2 also had a lot of hardware problems, but it still came out on top.
In the end, I don't care which console wins, because it's not a competition. What console you like should be your own thing to enjoy, not defend on an internet forum.
