And when I say PS3 I mean just PS3 not Xbox 360 here's why:
For PS3 owners, there's no word just yet of new game announcements. But we think news of a Final Fantasy XIII demo is just as good. Square Enix announced that it will bundle a demo version of FFXIII with the Blu-ray release of Final Fantasy VII Advent Children. In addition to a playable version of the first FFXIII series title, the disc will also contain new footage of Versus XIII and Agito XIII.
Advent Children Complete, as the Blu-ray version is called, hits Japan in March 2009. In addition to a standalone release, Square Enix is planning a hardware bundle that combines it (and the FFXIII demo disc) with the PlayStation 3 hardware.
