That is the crappest idea ever. Mixing Nintendo characters with XBOX and PS characters. That would just get so crap. Imagine, just a load of bull wang. Super Smash Bros is unique, nearly everyone who has a gamecube has SSBM and i think that the same will happen to SSBB and the Wii. But thats not my point, Icetrash is correct. It would just 'fun' it up (fun meaining F***) It would just feel queerish fighting mario against Jak and that Halo dude. Or Ratchet. I mean they are all cool characters for their consoles but there just not meant to mix together. Its like dragonballz and pokemon. No one is gonna watch Pokeballz. It would just be weird. Imagine Goku kamehamahing a pikachu.... Strange. Thats what a combination of characters from nintendo ps and xboxb would be like.
