The original plan was for Nomura and his team to finish Versus XIII before going to work on KH3...this was of course before PS3 launched in 3rd place and before they hit developmental problems. Versus is supposed to follow up on FFXIII, but they're not supposed to put full resources towards Versus until they finish the White Engine, which means that any work on the game is moving at a snails pace. And if anyone's been keeping up with FFXIII news, they know that's not going to be for awhile, because last I heard, they didn't even have the game running on an engine yet. Versus would be lucky to come out in 2009.
Now, I know Square Enix, let alone DISNEY, isn't willing to wait forever to put out KH3, so I'm expecting it to go into development before they finish Versus. Of course, not this year. This TGS is about the spinoff series.
