There is a new Wii model coming on December 7. The Wii Mini, will only be sold in Canada for the holiday season for $99.99. Nintendo is not ready to talk about release details for areas outside of Canada at this time.
As the name suggests the Wii Mini is smaller than the original Wii, and is colored red and black. It also has a matte finish instead of the traditional white or black glossy finish. The Wii Mini will ship with a red Wii Remote Plus and a matching Nunchuck controller.
Nintendo notes the Wii Mini cannot connect to the internet and is not backwards compatible with the GameCube.
