All right, time to try this. ANOTHER PLAYSTATION ALL-STARS ROSTER PREDICTION.
(also the game already looks like it'll be better than Brawl. But then again, I view Brawl to be extremely overrated so I guess my opinion there should be taken with a grain of salt...)

Sweet Tooth (Twisted Metal)
Fat Princess
Sly Cooper
Colonel Radec (Killzone 2)
PaRappa the Rapper
Nathan Drake (Uncharted)
