Does not matter how much you sell if losing money. Why Wii U sales are not killing Nintendo,Still making profit.
Wii U isn't making money though, Nintendo's been in the red since each year since the Wii U launched and they've stated in their annual reports that the failing Wii U business is the reason. I'm not sure where you're getting that graph from but 2013 was most certainly not a profitable year for them.
