If history has shown nothing else, it's that Japan loves Final Fantasy. So we expected the debut of its newest full sequel, Final Fantasy XIII, to make big waves in its homeland. Kotaku reports that in its first day alone, the game sold over one million copies. The number doesn't include the PlayStation 3 "Lightning Edition" bundle, which most likely moved impressive units as well. This puts a dent into Square Enix's retail base, which shipped two million copies for the release, but Japanese fans and importers shouldn't have too much trouble finding the game.
By comparison, another beloved Japanese franchise, New Super Mario Bros Wii, sold over 900,000 units in its first week in Japan. That was enough to steal the record for fastest-selling Wii game, but doesn't hold a candle to FFXIII's first-day success. When the game launches in the U.S. in spring of next year, it will be on twice the number of platforms, but American sales tastes have been moving progressively away from the JRPG. We'll have to see if the Final Fantasy name can still inspire massive sales here as well.

I don't think it is going to be as good on the 360 because it is the first one that is coming to it. Plus i think there is more of a fan base on ps3 for this game

only part of it is coming out for 360, there will be single and multiplayer, and 360 will only get one of those and only PART of it. Less game features and supposedly only HALF as much stuff into the game as on PS3

They've been saying it since they started the release.
