Final Fantasy XIII Story Is Just About Finished

Should hope so too... Australia’s Official PlayStation Magazine had some time aside with Final Fantasy XIII development boss Yoshinori Kitase who has confirmed the story is pretty much done:

“The scenario is pretty much complete and the artistic side is about 80 percent complete."

Kitase also sung to PS3 owners ears confirming the team's concentration was on the PS3 version of the game which would then be ported to Xbox 360:

“The team is looking to specialize it for the PS3 so that the game will be maximized [for that console], and then they will port it over to the 360 and utilize the capabilities of that console."
