Windbane, you're really stretching with your exclusive AAA argument. I'm going to assume you don't know this, because look here:

Oh, look at that. Using your method, the 360 only has had 3 AAA exclusives so far. The PS3 has had 2.
I guess this console gen has been really awful, huh?
OT: MadWorld has a shot. If it doesn't make it... it will be a while for the next one. If you're including WiiWare, it's possible a breakout hit will pop up, but if not, it'll be something that comes out in the holidays. Not that I care that much about metacritic scores anyway...
