Final Fantasy 13 Demo with Blu-Ray Advent Children?

It would seem the DK Σ3713 Party has a bit more information to offer that I guess I must have missed. 1up.com is reporting that with the news of Final Fantasy 13 going to both the PS3 and Xbox 360, Square will be giving the PS3 users only (clearly because there the only ones with a blu-ray player,) a demo of Final Fantasy 13 with their purchase of Final Fantasy VII: Advent Children.

However the said release of Advent Children is estimated around March 2009... so in any case everyone loses because damn that is so far away :(. But like the editor at 1up suggested, that doesn't really mean the 360 couldn't get a downloadable demo, we'll just have to wait and see.
