Wii digital content can’t be played on the GamePad, transfer process tidbits

Nintendo has confirmed that all Wii digital content won’t make use of the GamePad. That means you won’t be able to play Virtual Console (or WiiWare) titles on the controller.

In order to transfer digital content from a Wii to a Wii U, you’ll need both systems and an SD card. It’ll work very similarly to the DSi to 3DS transfer process.

One other important note: Nintendo of America won’t confirm that the transfer tool will be available at launch.
