Wondering if you should get a Wii U? Well, Mario Kart 8 is more than enough reason to justify purchasing one. Today Nintendo President Satoru Iwata announced that the next installment of the Mario Kart franchise will race its way onto the Wii U in the spring of 2014. The tracks are even crazier than ever with anti gravity, loops and swirls. This version will also have bits and pieces from its previous predecessors.
