Wii u sold just shy of 4 million by end of March last year with minimal sales made in February and March. We are only at 5 million currently and moving into the dead period of Jan-March where not many will be sold.
So only about a million consoles have been sold approx and thats despite a few key titles being available for the christmas period. Mario kart may sell consoles but going by its release date and how much business Mario 3D World did I'm not optimistic.
I think its clear wii u will probably sell poorly. Through most of 2013 the original wii was often outselling it, at least in Europe and that may continue in 2014. I think Nintendo are going to be under a lot of pressure to reduce the wii u price or it simply won't be stocked by many retailers.
