I've been seeing this make the rumor mills lately. Honestly the idea that Ito has been developing XVI in the background would be wonderful especially since he hasn't really done anything substantial since XII. I'm of the "I'll believe it when I see it" crowd as I find it hard to believe it has been in development this whole time and SE, who usually jump at the chance to announce a new FF IP, hasn't said a word about it. I mean right after Versus XIII got changed to XV, the SE I know would have probably released the title image for XVI right after to get the fanbase a buzzing.
