Nintendo has filed Trademark for the name Zii. Huge mistake for such a large company since Creative already owns it. Could be they want to call the next Wii, the Zii, but Creative might disagree.
The trademark recently popped up on the Japanese trademark database. The filing covers video games and electronic devices, but contains little information. Our guess is that it might be the HD Wii that we’ve heard rumors about. Hopefully more info will come soon.
