Probably what's going to happen is they'll finally make a succesful spinoff series which will eclipse the main series's popularity (sorta like how Capcom stopped making Mega Man games 'cause Mega Man X was selling better), at that point there'll be a few periodic FF releases, but they'll just shift focus. At the moment I'm hard pressed to think of a series that made it up to a 12th installment, so that in and of itself is pretty impressive. King of Fighters made to to a 10th game, Mega Man and Dragon Quest have only gotten up to 8 so far.... Actually managing to keep consumer accomplishment for that long is such a huge accomplishment it's really quite unusual for a company to do that.
