I wouldn't count on it, Final Fantasy Versus 13 is still on the PS3 as a exclusive and that is the system the KH team has worked on.
Anyway the Sony Conference just ended, it was better than the Nintendo one, although that isn't saying much. There was nothing jaw dropping like FF13 losing it's exclusivity, but it had nice trinkets, like DC Universe, the PS3 Movie store debuting tonight, God of War 3, and MAG.
Edit: How could I forget Sackboy doing the financials presentation. Best.Financials.Presentation.EVAR!
