It's left to Xehanort. Seriously, how can KH replace one of the most egotistical, megalomaniacs in any form of fiction? What is left beyond the Xehanort Saga, and is there any possible chance that it won't have been started by what Xehanort set in motion?
Probably not. We know that Xehanort's ultimate goal (an odd ultimate goal) was to reorder the universe (worlds) where light is the side looked down upon and darkness is the major power. He wanted the X-blade to reunite the Keyblade Wielders throughout the worlds (so now we have some setting for future events) and ultimately change the world order. "You would risk an apocalypse out of sheer curiosity?!" Yes, yes he would.
Like him or hate him (I'm trapped between o.o), he's Xehanort and KH won't be the same without him.
