Bad news for those of us who were hoping that the lack of a Wii trademark indicated a Nintendo marketing conspiracy to change the name back to the Revolution come E3. The trademark database has been updated and, sigh, Wii is there.

The US Patent Office link tends to like to die out, so we're not sure if it'll work for you, but you can see it in the screenshot above, and yes, Wii is indeed registered to Nintendo of America.

Of course, even as a publicity stunt, Nintendo would be likely to trademark Wii, right? Right?
