So, i looked around and couldn't find anything similar to this, so i'll just throw this out. Sora is going to save everyone, or at least try (but since its Disney... he will.), and i'm betting he will have to return to the Keyblade Graveyard during his travels, and who will be waiting for him?
Lingering Sentiment.
Now, we know LS isn't evil, and i'm betting he'll be a temporary party member. Which would be, in a word, awesome. There is also the possibility that with the power of Terra/Xehanort no longer 'split' between several forms, LS may be able to retrieve enough power to take an active role, rather than just waiting. Which would also be awesome, who wouldn't want to see LS battle Terranort, who summons Ansem and Xemnas to fight alongside him.
Yeah... that'd be confusing.
