FF13 won't sell bad, it just won't sell anywhere near what a FF game should and will probably doom Sony's relationship with Square-Enix. Not that it matters, most of everything they're making now-a-days is either a remake or crap.
the problem is, even if Final Fantasy sells as many as FF12, and every single person who buys it buys a new PS3, it STILL won't catch up to the Wii
One game can move a few consoles, but it takes a lot more than one game to move a large amount of them.
Final Fantasy 13 can prove, however, that even a huge game might fail if released on the PS3. Or it could prove that huge games if done well can succeed on the PS3 as well as they did on the PS2. but single-handedly win the console war for Sony, it won't.
you need a large number of quality games to win the console war, and I don't think Sony's going to get enough
