FFXIII Anagram Solved: Announcement Nov Thirteenth
Well that didn't take long. Forum members hintonmj and Squirrel Emperor have already worked out the anagram posted by Square Enix about an hour ago. The anagram says "Announcement Nov Thirteenth" so we're obviously going to find out something then.
It could be plenty of things ranging from the announcement of an English demo or the confirmation of a Western release date but it looks like we'll have to wait a week to find out what they're holding from us.
