Yangus: Mysteriously Absent?

So, Young Yangus' Mysterious Dungeon does not seem to be appearing on American shores any time soon, which really sucks. However, something that escaped me at E3 but now has me totally psyched: Square Enix announced Dragon Quest Swords: The Masked Queen and the Tower of Mirrors for release on the Wii. Unclear if it will be an exclusive. The press release says that the Wii hardware is integral to the gameplay, so if they port it to PS3 or whatever it will certainly be a different game in some respect.
