Fumito Ueda confirmed earlier today that The Last Guardian is slated for a 2011 holiday release. Not to mention that it'll support 3D. During the press event, Ueda also noted that the main character was originally a girl, but that changed for two reasons. One being that it made more sense for a boy to have a better grip than girl when it comes to climbing and the other that the girl would be wearing a skirt. No points for guessing why that would be a problem.
A new trailer has also been released for The Last Guardian and it is absolutely gorgeous. Sit back and try not to cry over the fact that we won't be seeing this game for another year.
