The Wii U is making a strong case at being a good 2nd console next to the PS4. It has a lot of upcoming games that can only be played on the Wii U. 3rd party games on the X1 aren't that much of a selling point when they look and perform better on the PS4. The X1 has exclusives, too, but it has already lost the exclusivity of Dead Rising 3 and Ryse to PC. Considering how poorly it's selling, we might be seeing other exclusives like Quantum Break going to PC, too. This is something you'll never have to worry about from Nintendo.
