Wii Mini Console Scheduled for December 7 Launch?

As with any new console launch, the recently launched Wii U system is in short supply. It's shaping up to be this holiday season's hot item, but it might not be the only console Nintendo launches before the end of the year. Rumor has it there's a Wii Mini slated for a December launch.

Citing a release schedule from a "major retailer," Nintendo World Reports says the Wii Mini will be released on December 7, 2012, though few details are known about the rumored refresh. Here's the internal ad the site was supposedly able to obtain:
Introducing the Wii Mini! Coming Dec 7 2012!
Wii Mini Console
Compact Nintendo Wii Console
Comes with Sensor Bar, Nunchuk and Wii Remote Plus with Jacket
Nintendo Consoles

The Wii Mini would represent the console's second refresh, and is particularly interesting because the Wii is already a fairly compact system measuring 8.48 inches (D) by 6.18 inches (L) by 1.73 inches (W).
