Square Enix has just confirmed a couple of differences between the Playstation 3 and Xbox 360 release of Final Fantasy XIII. In an interview in Famitsu they state that the video and audio is compressed on the Xbox 360 DVDs while the Playstation 3 version will be uncompressed and appear on a dual-layer blu-ray disc. The 360 version will obviously be released on multiple DVDs. This means that the uncompressed game will be 25GB minimum.
