I voted for Wii U, because I believe that Mario Kart and Super Smash Bros. could very well sell a lot of systems. To be honest, it's a toss up between all three to me, I have no idea who will be in the lead. I have already purchased a PS4, so I won't be adding another sale to it, but I have yet to purchase a Wii U, so I could add a sale to that. I am not very interested in the XB1.
