Wii U most likely launching sometime in the 'Christmas' seasonClick Here to View Story
Coming from last night's event...
"I believe that you are most interested in the details of the Wii U. Since the Wii U will be launched in Japan, the U.S., Europe and Australia in the year-end sales season... as we did for previous platforms that were launched in the year-end sales season, we will announce the launch date and price in each market sometime after E3."
The 'year-end sales season' pertains to Christmas shopping. Once again, this makes a November release very likely for the Wii U.
