As promised, Yoshinori Kitase posted his announcement on the European Playstation Blog just moments ago. The announcement is in video form but it's loading extremely slowly because of thousands of fans trying to watch it all at once. Try your luck at trying to view it for yourself below. I have to say it's maybe a bit overly epic for what it is.

For those of you who want to know now, here's all the details announced in the video.

Final Fantasy XIII is coming March 9th in North America. We assume it's a simultaneous release with Europe from the way it was revealed in the video but I'm sure we'll get confirmation soon.
Leona Lewis will be performing the theme for the English version with her song song "My Hands".
The video includes never seen before battle footage as well as the first time we've seen Chocobo's being ridden in motion.
