Apart from that there's two things more I gotta mention.

The first is that we know where Ventus's heart is. It's... been inside Sora, all along.

The second is... well, it's worse news. Master Yen Sid has told me that when a Heartless is destroyed before a Nobody, the two halves will rejoin... and reform.

Xehanort, the original Keyblade Master, has returned... and we don't think he's alone, either.
