Oh and http://www.siliconera.com/2011/07/12/xehanorts-last-game-will-be-kingdom-hearts-iii-but-sora-will-still-be-the-series-protagonist/ found it much quicker than I thought I would.
Also apparently I remembered it wrong. Sora will still be the protagonist after 3, it's just the villain that will change.
