Another English trailer has surfaced online, thanks to Gametrailers.com! Check it out:
The trailer reveals that Christopher Lee may be playing DiZ (please take this with a grain of salt; it's hard to tell if it's Christopher Lee or Corey Burton) while David Gallagher will be returning as Riku. Naminé is also heard in the trailer, who sounds a lot like Meaghan Jette Martin. (take this with a grain of salt as well!)
