Edit: Found scan and Gamekyo's take on the article:
- Play at the same time on the Wii and DS, thanks to Pollux Engine created by Square Enix.
- Players on the Wii and players on the Nintendo DS will be able to play online together.
- Different gameplay for the 2 versions (stylus or Wiimote).
- Story revolves around Charlotta and a mysterious crystal.
- You can transfer Mii characters you made to the DS version.
