They can't be a success any more IMO, you get one chance in the MMO world and once your game is marked as "CRAP" that's it people don't want to know.

Even most PS3 player are going to stay away form this game because the PC version had such bad reviews and word of mouth.

Not to mention SE have to compete against Blade and Soul which is also coming to PS3 and is light years ahead.

TL'DR:- PS3 isn't going to save this game.
