Say if Nintendo was ever on the verge of going bankrupt somehow, their console isn't making any money and neither is their handheld, however they can't abandon either but the base ideas just aren't appealing, this also applies to the Wii U despite them not being in any trouble. If Nintendo ever got so desperate to where they HAD to make a turnaround they just would have to develop one game that would instantly turn whatever console into a success.
3D Pokemon MMORPG.
If the Wii U had a 3D Pokemon RPG, or just a 3D Pokemon game with the same mechanics as the mobile ones, then even non-nintendo fans will jump aboard, including the millions who play pokemon simulators on their comps. So to be honest, Nintendo doesn't have to worry about leaving the game industry with this ace up their sleeve. Sony and Microsoft don't have things remotely as saving as that would/could be.
