According to the official Nintendo Wii website, the next-generation console will go on sale on Saturday, December 2, 2006, in Japan, and in North and South America, Sunday, November 19, 2006. Pokemon Battle Revolution is a Wii title and will go on sale December 2006. Many North American stores will begin pre-orders of Wii for $50 starting Friday October 13th, 2006. Approximately 4 million Wii consoles will be available at launch. Unlike DS, Wii will uphold Nintendo Gamecube games region lock and all Wii games will be region encoded. It is unlikely that a North American Wii will play an imported version of Pokemon Battle Revolution.
