On a side note: what about Eraqus? I believe his heart joined Terra's. Will he (can he?) be ressurected somehow?
Finally: what the heck is exactly the Guardian of Xehanort/Ansem? It didn't appear until Xehanort's takeover of Terra, though it doesn't seem to be exclusive to him, since Riku was able to channel it and use it against Roxas in Days (though he assumed Ansem the Heartless form in order to do so). It's a "pure" heartless, but whose heart was it born? I'm still wondering if it isn't Eraqus's heartless, but I guess this idea is a tad far-fetched (though, well, if he manifested from Eraqus's darkness and became a twisted version of himself as Terra's protector...).
As for Xion: I wouldn't mind her being "reborn", though I agree that there shouldn't be too many easy ressurections in the KH verse. Poor girl/puppet/thing had it rough. What is she at this point? Nobodies can grow a new heart, but what about someone as "special" as she is?
