I for one certainly think that Wii U will do better as long as Nintendo can release games often enough. Mario Kart 8 alone gave Wii U a huge boost. It is possible that Hyrule Warriors will give it a nice boost as well. I doubt Bayonetta 2 will make a dent, but Nintendo 1st party games can make Wii U a bigger success than Xb1 if Nintendo can make them fast enough.
I really hope Nintendo wipes the floor with Xb1. Go Wii U!
