This new model will have a few variations from the current Wii.
Earlier today, Official Nintendo Magazine's website was updated with a news story revealing a new version of the Wii console. This new console is quoted as being "streamlined," and will officially lay horizontally, lacking a vertical stand. This particular Wii will be released "before Christmas," and will be bundled with Wii Sports and Wii Party. In addition to the changes above, this Wii model will not include GameCube controller ports, and will not be compatible with GameCube games.
