its not the "iconic" characters that will be a problem in this game, its that most of sony's newer big hits have incredibly bad characters for a fighting game at least a super smash bros stype one. Killzone, Resistance, Uncharted, Gran Turismo, Moterstorm, etc. etc. have terrible characters to include in such a game. The only popular ones that would be interesting are sackboy, kratos, Col, Ratchet, Clank, and their older mascots. The problem is many current ps3 owners don't care for or haven't even played games with sony's classic mascots. Super smash bros includes the most popular nintendo characters ever, and those are the ones that sell the game while the lesser known characters please the hardcore crowd. Sony's equivalent popular characters would be generic army guys from call of duty, gangsters from Grand theft auto, and cars from gran turismo. Doesn't really sound too awsome does it.
