Given that he and Ito say the exact opposite in the interview given in the Square-sanctioned Ultimania, I'm going to go ahead and assume that is (as is often the case with these interviews) a rougher translation that loses some of the nuance combined with Kitase merely being humble. From the moment the starting pistol was fired on FF6 he and Ito were joint directors and Sakaguchi was merely overseeing. The 1up interview doesn't overturn multiple other sources, sorry - especially with how unreliable those on-the-fly translations can often be. Take it from me, I've done enough of those interviews in my time!
I think you'll be disappointed, tbh.
I think SE feels the Tabata promotion has been quite successful and fresh blood is a potentially very good thing. I also think while Ito's genius is undeniable, it's also true that the two FFs he directed solo (or more or less solo - 9 and 12 - are two of the least-selling post-FF7 FFs. Even FFX-2 sold more than both, in fact. Ito may well be better as a systems man and an idea man than a director, at least if you're talking about mass-appeal and major sales, which is what they're chasing now more than ever. Ito may be better working on concepts and trying to flesh out something revolutionary even if it doesn't turn into a real product than directing a game.
If you're looking for some Tabata style new blood, there's a lot of names and faces who have either been in the background on FF for a long time or who have been directing B-tier SE games for a while. For instance: Hiroshi Takai (The Last Remnant Director, Battle Director on several SaGa games, Lead Planner on The Bouncer, and Assistant Director on FF14), Taro Yoko (Nier, Drakengard - outside Square but precisely the sort that could be tempted to join to direct a major project), Hiroki Chiba (Lead Event roles on CT, CC, FF7 & 10, Lead Writer on Type-0, Writer on LR:FF13, Event Director on FF8).
I wouldn't even write off the chances of somebody unexpected like Watanabe just catapulting up to a Directorial position. These kind of jumps are how the likes of Kitase and Nomura got their first big breaks, too, and currently the company is on a Tabata and Yoshida - both relatively unknown - high. They'll quite possibly want to replicate that success. Notably, it is usually the Writers, the Artists, the Planners and such who go on to Direct - not so much the Programmers. In that respect Ito is the odd one out.
Disclaimer: I'm a huge Ito fan, 9 is my favourite FF. I'm also a realist, however.
