"Kingdom Hearts 3 depends on Final Fantasy XIII Versus"
I think what Nomura means is that once Final Fantasy Versus XIII is in the stages where it's almost complete and the engine is totally pumped up, Nomura will start making Kingdom Hearts III on the same engine, which means it's gonna be at least on the PS3.
So now that leads me to thinking that it Nomura didn't build the engine used in Versus XIII just to make one PS3 game. He definitely has plans to release other games using his engine on the PS3.
Also I've got a rumor about an unannounced Kingdom Hearts Game that may relate to Nomura's other two Kingdom Hearts Games.

"Interesting news today, rumors have been circulating around the community about the next Kingdom Hearts title, supposedly as a follow up to Birth by Sleep's secret ending. The game, originally believed to be titled Kingdom Hearts: Deep Dive, is now referred to by an anonymous forum poster as Kingdom Hearts: Another Dive. A url referring to the game has surfaced, however, the page does not go anywhere. Tomogirl has translated some additional information on the rumored title, below:
This is summary blurb on that particular page... (Possible spoiler? Although, it's not major sounding at this moment.)
Sale date: Unknown
Console: Playstation 3
Price: Undecided
Story: This is about a tale coming from a different viewpoint of what happened a part of (or in addition to) the world in which Sora obtained the Keyblade....
What could this mean? A game about the adventures in the Dark Realm?"
Of course this is all a rumor and nothing is confirmed but this was originally brought up in 2ch in Japan. I can't say it's true but I hope it is.
I believe in Nomura
