Sony has the quantity characters to do it, but their characters are so diverse that the atmosphere of such a game would be ridiculously convulted.
Kratos w/Chaos Blades vs. Nathan Drake w/Pistol vs. Buzz w/Buzzer just doesn't work like Smash Bros. does.
Sony is better off pushing their brand games/characters off more on games they already have such as LittleBigPlanet, Hot Shots Golf/Tennis, PAIN, ModNation Racers, and PlayStation Home. If Sony feels the need to make a fighting game then they should only include other 1st party characters that work well and wouldn't unbalance the game such as Kratos and Nariko.
