You do realize that Final Fantasy XIII is laid over a multiplatform gaming engine developed by Square. Which not only means they are fully fluent in their software, but the base of the game makes for ease in porting the title correct. Further more you should also realize that the title was fifteen percent complete during summer of last year.
The title should fall early summer next year in Japan, and probably the fall in the rest of the world. Square has placed quite the premium on quick localization as of late, and thanks to the hardware in both the 360 and the PS3 localization is far better this generation. Hell if Mistwalker can do Lost Odyssey in a few months Square can most assuredly do so.
Your getting all knotted up over nothing.
