Tetsuya Nomura is the director, concept artist, and character designer of the Kingdom Hearts series at Square Enix. He’s said in an interview with Japanese magazine Dengeki PlayStation that Disney wishes Square Enix would develop Kingdom Hearts III.
Quote translated by Kotaku says: “We’ve already been approached by the Disney side saying that they want us to make it. What I can say at this time is ‘We have various ideas, but we’re not at the point where we can say that.’ It’s physically impossible at the present. I feel that it’s not the right time to talk about the future of Kingdom Hearts.”
Yeah, he’s kind of busy at the moment with work on the Fabula Nova Crystallis: Final Fantasy XIII projects as the character designer of all three games and the director of Final Fantasy Versus XIII, as well as the character designer of Crisis Core: Final Fantasy VII for the Playstation Portable. Aaaaaand he’s also in the development team of the title It’s a Wonderful World for the Nintendo DS.
