Nintendo Files Trademark For Zii, Is It The Wii 2 Though?

If Nintendo's follow-up to the Wii is actually called the Zii, I think that's the first mistake right there. But could this mysterious trademark, filed in Japan in October, actually be for the Wii 2, or something else?

It was spotted on a trademarks database yesterday by the eagle-eyed Siliconera, who rightly points out that it "seems kind of late to protect Wii typos since the console is three years old." Perhaps it's that HD Wii which has been oft-rumored? Whatever it is, Creative won't be too happy. [Siliconera via Kotaku]
