Found an interesting bit of info while randomly browsing wikipedia:
The source is listed as Dissidia's Ultimania guide which was published last March, so the info is more than a year old. Pretty interesting nevertheless, as "large-scale" combined with Ito leading development very strongly suggests Final Fantasy.During the creation of Dissidia 012: Final Fantasy, the battle system director, Takeo Kujiraoka, attempted to consult with Hiroyuki Ito about the fighting style of Vaan. However, due to Ito being busy leading development of large-scale, unannounced project and also not being an employee of 1st Production Department, Kujiraoka could only reach him via e-mail.
For those unfamiliar with Ito, he's been with the company since 1987 and has been responsible for lots of good things about the series. His main roles include creating both the ATB system in FF4 and ADB system in FF12; developing the job systems in FF5 and FFT; the materia system in FF7; the junction system in FF8; and directing FF9 and FF12; leading development on FF12 IZJS; and event planning/directing for FF6 and Chrono Trigger. Not to mention he is highly regarded by both CEO Wada and Hironobu Sakaguchi, the latter of whom has said that if anyone can save Final Fantasy, it's Ito.
Overall, not too shabby a résumé. If he does happen to be in charge of the next FF, I'd say chances are it'll be a good one.
