Final Fantasy XIII-2 domain name registered
This domain name could simply be Square Enix grabbing related names just in case, but it could also be evidence of a direct sequel to Final Fantasy XIII — possibly, like Final Fantasy X-2, one built on the engine and assets from the previous, expensive game. Of course, unlike Final Fantasy X, the Final Fantasy XIII "franchise" is already somewhat crowded, with Final Fantasy Versus XIII and Final Fantasy Agito XIII on the way sometime before the end of the universe.
Square is holding a "1st Production Party Premiere Event" in Japan on January 18, so if there really is a new Final Fantasy to announce, we'll likely hear about it, and any costume-change-based fighting it may contain, then.
