Price cut: the deluxe Wii U is now $299, same price as the basic model. I suspect the basic model will go away soon.
The Legend of Zelda: Wind Waker HD is launching on the eShop on September 20, with the boxed version showing up later on October 4. There will also be a system/Wind Waker bundle, also priced at $299.
Wii Party U is out on October 25. Super Mario 3D World is out on November 22, and Donkey Kong Country: Tropical Freeze is December 6. Wii Fit U and Mario & Sonic at the Sochi 2014 Olympic Winter Games (I wonder if Birdo is a playable character?) are also scheduled for "this holiday season."
