The Wii U just got released, but a report from My Nintendo News stated that a redesigned smaller Wii console could be released. They state that it would be released next month, possibly on December 7th.
The name would be the Wii Mini. It would include a sensor bar, Numchuck, Wii Remote Plus, and a Wii remote protective jacket. There is no information on pricing at the moment.
