I want this, a USB dongle that plugs into the Wii U and its just a 3DS/DS card reader nothing more. All it does is reads the data off the DS/3DS cart and runs the game on the Wii U. I do NOT want a stupid Virtual Console filled with DS games playable on Wii U what I want is an actual device I buy and plug it into my Wii U and can plug in those carts and play them on my TV, or Game Pad as I see fit. This is a win-win for Nintendo they sell a device at a reasonable cost its a hardware sale, then they sell tons more DS and 3DS software to someone not interested in the hand held device.
Just bringing those games to Virtual Console is not going to cut it because it would be one damn game a month and who has time to wait around for that? Who else thinks this might be a doable solution? Would you buy this device if it existed? It could even support New 3DS software if they wanted to. Maybe this will get announced at E3?
