Lets make this clear; NO console bashing in this topic. Nada, none.
The FFXIII compilation has been in and out of gaming headlines since 2006, and I daresay it deserves its own topic here as it could be the saga of gaming which defines 2009. So far, we know that there will be three games in the XIII compilation, and there is allegedly a fourth in production:
Final Fantasy XIII (PS3, Xbox 360)
Final Fantasy Agito XIII (PSP)
Final Fantasy Versus XIII (PS3)
Despite the games sharing the same name and backdrop, they will be entirely independant of each other rahter than being sequels, where Xbox360 and PSP players would miss out. Each title will have its own style of gameplay: Final Fantasy XIII is an RPG, Final Fantasy Versus XIII is more action-oriented like Kingdom Hearts, and Final Fantasy Agito XIII is an online game, having a battle style similar to Crisis Core: Final Fantasy VII. And although the development for each title is being handled within Square Enix through separate teams, the character designs for the three officially revealed games are by Tetsuya Nomura, who is also the director of Final Fantasy Versus XIII.
The Demos of Final Fantasy XIII and (?) FFXIII Versus will be playable on the Final Fantasy VII Advent Children Complete bluray disk in Japan towards the end of March, with the release in America and Europe rumoured to be around April 09.

There are a few more trailers and TV spots in circulation, however I'm too lazy to find them all .
My comment?
These games may be the defining reason why I will buy a PS3 -those games look mindblowingly brilliant.
