E3 2012: Wii saves and games can transfer to Wii U

Nintendo has confirmed that it is working on a method that will allow gamers to transfer Wii content to the Wii U.
This will include existing game downloads and save game information.
However, the platform holder did add the caveat this it is “preparing” the tech, suggesting that it has not yet been developed.
This of course leads to the possibility that the transfer system won’t be in place by the time the Wii U launches later this year.
Inconvenient, yes, but not unprecedented – Nintendo’s DS-to-3DS transfer system arrived several weeks after the 3DS itself hit the market.
Don’t forget, too, that Wii U is also compatible with a number of Wii’s accessories including the WiiRemote and Wii Fit Balance Board.
