Lots of things revealed in the trailer...

(SPOILER)
Axel appears to be alive

Vanitas is back... oh god...

Like fans thought, Xehanort has returned

Neku, Shiki, Joshua, Beat, and Rhyme from The World Ends With You have all been confirmed as characters in the game.

If the CGI trailer is anything to go by, we may actually see Master Xehanort return

Three Musketeers, Monstro/Pinocchio, Hunchback Castle, and Tron: Legacy confirmed as new worlds.

The new powers seen in earlier trails that Sora and Riku use are executed through the touch screen with the stylus.
