Instead of always being last place in the console race, they should only do what they are good at which is portable systems. Instead of WiiU or 3DS, just have the tablet. The tablet would act as a console in that you can connect controllers to it and stream the action to a television. Everything would be downloadable or made on cartridges and Nintendo's online system would need to be revamped to make the user experience better.
So they would basically be squeezing the WiiU into the Gamepad and releasing ALL their rehashes on ONE system. No more buying the same Mario Kart, Super Mario, Zelda, Pokemon or Donkey Kong two different times for two different systems. One console-handheld hybrid that can stream games to a TV and habdle four players.
Whatcha think? Genius?
