The Wii U console will support Wii software, including physical Wii games, Virtual Console titles, and WiiWare. However, Nintendo of America has confirmed that you cannot play those games on the Wii U GamePad; you can play them with a Wii Remote or Classic Controller as they can connect to Wii U.
This is similar to Wii’s backward compatibility – Nintendo GameCube games are playable on most Wii consoles but do not work with any of Wii’s controllers. Remember, Nintendo GameCube Game Discs are not compatible with Wii U.
