Nintendo confirmed that saved games on Wii's Virtual console will not be transferable to the Wii U's Virtual Console. Although such a seamless exchange would have been welcome, it's really not the end of the world.
Gamers can still access Wii's Virtual Console on the Wii U through the use of the menu, thus enabling gamers to play Super Nintendo and Nintendo Games on their GamePad or Wii U. Purchased Nintendo and Super Nintendo games on the Wii can be played through the Wii U by transferring the Wii's data to the Wii U and accessing these titles through the Wii Menu.
Gamers can also, if they pay $1 for NES games and $1.50 for SNES titles, repurchase the games for the Wii U's Virtual Console so they can play on the GamePad and be accessed directly through the Wii U's menu. Repurchasing these games for the Wii U will not enable gamers to access their save games from their Wii Virtual Console. That linear exchange, even with all the expanding abilities of the Wii U, is still a fantasy.
