Today twitter seems to be useful again because SquareEnixSonia (Square Enix PR division) revealed that some people will be able to play FFXIII soon, probably on the 13th.
This is her tweet:
Official tomorrow but heads up! Bay Area folks will get a chance to play #FFXIII That is if you can find us! #FinalFantasyXIII @playFFXIII
Earlier she posted this tweet:
Guess who I started following today? @PlayFFXIII If you're in the SF/Bay Area you might want to do the same #FFXIII #FinalFantasyXIII
Tomorrow we will probably get more information.
