Nintendo has changed the name of its next-gen consol from 'Revolution"? to 'Wii"? (pronounced 'we"?).
Interestingly, it appears Nintendo has not yet filed Canadian or American trade-mark applications to protect the new name. Perhaps Nintendo has filed applications in Japan. If so, and if Nintendo files the same applications in Canada and the US within 6 months of the Japanese filing date, then the Canadian and US applications will be backdated to the Japanese filing date.
