On the PlayStation 3, Final Fantasy XIII will ship on a single Blu-Ray. Avantage of the format! On the Xbox 360, however, the game will - as expected - ship on three discs.
Sources at Square Enix USA have confirmed with Kotaku the reports from yesterday, which have settled a long-running - if ultimately pointless - debate amongst fans of the series.
We say pointless because for a game like this, three discs aren't so bad. After all, Final Fantasy VII came on three discs. And the 360's other big Japanese role-playing games - Mistwalker's Blue Dragon and Lost Odyssey - shipped on four discs, and people didn't seem to mind that either.
