Nintendo has accepted Unepic to be published for WiiU.
EnjoyUp, a company in Barcelona (Spain), will be the publisher of the game. They have already done games for Wii and Gameboy, and published other cool products like
La Mulana.
The porting will start next January. When the porting is done, I will have to do all changes in the game coming from Nintendo, specially in dialogs and some 'adult-like' quests ;-)
It is too early for a prediction, but the game could be available in May 2013.
