IMO Nintendo has abandoned all hope for Wii U and they will only support it over the next 2 years to the extent necessary to allow their next hardware move to not launch in a complete Nintendo vaccuum. Which IMO means trying to sell about 3 million consoles in 2015 and in 2016 after they announce all new hardware to sell another 3 million Wii U's between the announcement and launch, which will be about 18 months. So 17-18 million Wii U's sold LTD by the time their next gen starts, and a rapid exit from the market after that.
