There has been a rumor flying around that the Final Fantasy XIII demo (the one that shipped in Japan with Final Fantasy: Advent Children Complete) was in fact 5.9GB. For those of you who are wondering why this is a big deal, think of it this way:
The demo was approximately 30-60 minutes long, and while Sony´s Blu-Ray can hold up to ten times that, its competetor's media format can not. So what does this say for the Xbox 360's version? Who knows, but it seems as if the PlayStation 3 version will be the one to look for.
The Blu-Ray Disc holds 45.9GB of data on it. Final Fantasy: Advent Children Complete takes up about 30GB of that due to the fact that the video runs at 27.8MB/s and the audio tracks (one English, the other Japanese) both run at 1.9MB/s. Couple this with the trailers and excess data on the disc and it makes up about 40GB. So what fills the other 5.9GB of space? Why, the demo of course.
So the real question is, will the Xbox 360 version be of lesser quality than the PlayStation 3 version, or will the PS3 version be downgraded to match that of the 360s?
