Yeah, except no one knew of IX's existence before it got re-branded. Whereas Versus XIII has been in a very public development hell for six years.

Still, though this particular rumor is false, I still feel it's very plausible that Ito is in fact woking on FFXV (unless the other rumor of Versus XIII getting a name change becomes true) since he has been largely silent in the background of SE since FFXII. He's got one iOS game coming out, but I hardly believe that took six years to make.
