We know when Final Fantasy XIII is arriving in Japan (December 17). Outside of a vague "2010," however, Square Enix hasn't told the rest of the world (specifically me) when Final Fantasy XIII is coming. Square Enix teased an anagram on their website over the weekend, though, which Final Fantasy XIII.net hacked away at before coming up with something mighty interesting.
"A Henchmen Inventor Tent Unto" suddenly made sense as "Announcement Nov Thirteenth."
It's speculation on my part, but there's very little Square Enix could surprise us with at this point about Final Fantasy XIII that would warrant a tease -- in English, no less -- other than a solid release date for the game. The only question is... will they make us wait till next fall? Oh, the river of tears.
