GTA / Madden | Fifa / CoD | Battlefield / Mario-like platformers are on iOS right now. Most of them quite decent. They'll get better if an official Controller (or) an API is launched. I think there's an opportunity for a proper platformer IP exclusively made for mobile seeing as how its exploding onto traditional consoles (Ouya/etc)
Remember Nintendo's investors threatened the board and wanted them to release Nintendo IP on Mobile appstores .
