Microsoft didn't just land an A-list RPG... they landed THE A-LIST RPG.   Me and a coworker were trying to follow the keynote as best we could, but once I heard that the SQUARE-ENIX President was closing the show, it really got my hopes up. 

Sure enough.

Biggest Surprise of the day by far.  I actually contemplated getting a PS3 specifically for this and 2 other games (MGS/GT5).  I played Prologue and wasn't impressed with it compared to my current favorite after-Ava-and-wife-go-to-bed-beer-drinking-funtime-game GRiD, and now with the announcement today FFXIII is coming to the 360 I am a very very happy camper.  If I didn't already have the 360 playing  Netflix streaming movies via the Media Center hack I would be just as happy about the new integration of that service with Xbox Live also.  Will certainly be nice to have an 'official' version though.

UPDATE: I also gotta give huge props to the Fallout 3 trailer.  Very well done and I admit, it made me pee a little in my pants.
