So popular people, such as Let's Players, can play the games without emulation/in crappy quality. Plus, it just would be cool. How it would work: Connect your 3DS/DS to your Wii U with the game inside the handheld, and you can play it in full screen glory, the Wii U touchscreen the touch screen, the TV screen the top screen. Sign, I WANT THIS!! And probably millions do to.
