Like Final Fantasy XII before it, it looks like FFXIII will be a huge game. But just how big will it be? Well, according to producer Yoshinori Kitase, the game will use all of the processing power of the PlayStation 3 console.

"Doesn't the demo use about 50 percent of its power? Of course, I think the retail version will make use of nearly 100 percent," Kitase told Dengeki PlayStation 3 magazine (translation via Kotaku). He also added that because of the space afforded by Blu-Ray and the PS3's hard drive, the game won't require any form of disc-swapping.

In Japan the game will only be seeing release on the PS3, so Kitase made no mention of the Xbox 360 version that will be coming to other territories. But if the title does indeed rely so heavily on Blu-ray and the processing power of the PS3, it makes us wonder how that will affect the 360 version. It's likely the 360 version will end up shipping on multiple discs.

While we still don't have a release date for the game, Japanese gamers are gearing up for the long-awaited demo, which will ship with the Blu-ray release of Final Fantasy VII Advent Children. As for when we can expect to play the full game, Kitase only said that "we are finishing up the tail end of the development."
