According to VGChartz, Square Enix’s latest RPG blockbuster has been flying off retail shelves as the reported 450,000 copies sold has been estimated as the day one U.S. numbers. Available for both the PS3 and the Xbox 360, the game has sold extremely well on both platforms for day one sale as VGChartz writes;

Preliminary day one sales are in for Final Fantasy XIII, and with around 290,000 units sold on PS3 and 160,000 units sold on Xbox360 it looks like the title is a success. With recent reports of 5 million units shipped worldwide, that likely breaks down to two million in Japan and around 1.5 million in each of the Americas and Other Regions (Europe, Asia, Africa, Middle East, Australia).

A day one figure of 450,000 should increase by around 40-50% by the end of the week meaning that around 45% of the initial shipment would have sold through in week one, with the rest of the shipment likely to last through to the end of April. The game launches in other regions on Friday and VGChartz expects a similar figure of around 500,000 units to be sold in the first couple of days with the PS3 version leading by at least 2:1.
