Yeah, and on a similar note, Square also registered the domains for Final Fantasy 12 through 15 (was announced many months ago already, though) so they plan on being busy in that series, too, at least up to 15.
They weren't for Chrono Cross, so I doubt they'd do sign him up for a third bout. They've also changed themes each go round, from time to dimensions. I'm curious to see if they're going to do it for this one, and how they'll beat out the last two.
