The GameCube had a GBA player. It allowed you to play GBA and GB games on your TV. It didn't make the GameCube a instant 80 million unit seller and it didn't slow down the momentum of the GBA. It was the DS that pretty much killed the GBA.
I'd be quite pleased with a 3DS player for the Wii U. Plug in adapter that lets you play your 3DS games on a big screen? I'd love it.
