During E3, it was announced that Final Fantasy XIII should be seeing a stateside release in Spring 2010. Square Enix was a little concerned about the number of discs required for the the Xbox 360 version of the game, and reiterates that the Playstation 3 version will be one disc long. As for retaining the original Japanese voices, Square responded only if it fits on the disc. Personally I am for the Japanese voices, as Vanille is voiced by Yukari Fukui, who also voiced Nia Tepplin from the anime Tengen Toppa Gurren Lagann.
The English voice acting also is a bit shaky, which you can decide for yourself after watching the included trailer inside.
