When I heard the concept I was like "Well, being a crossover fighting game doesn't necessarily mean it's just Smash Bros. with Sony characters."

Holy crap, though. :P It totally is.

Sony doesn't have enough instantly recognizable and classic characters to really pull this off as well as Nintendo does. I mean, that dude from Killzone is one of the announcement characters. Who even remembered he existed?

Maybe if Sony stuck with their characters across generations. :P I can't really think of any that have appeared on all three PlayStations that aren't third-party characters.
