If Super Smash Bros for Wii U and 3DS can't help Nintendo then I don't know what can. Mario Kart 8? Still though it's not a single game that will help the Wii U, but a long line of games. Pikmin 3, Super Mario 3D World, Zelda U, Bayonetta 2, etc. They just gotta keep pumping those high quality titles out. I was really surprised by the amount of information revealed with their Super Smash Bros Wii U 3DS Direct though: http://berathen.com/2014/04/super-smash-bros-nintendo-direct-ultimate-guide.php This level of attention and marketing to their games can only be a really good thing.
