If Nintendo discountinued the Wii U, third parties would be PISSED. Third Parties already have games in development for 2014 such as Watch Dogs and the Amazing Spiderman 2. These companies are putting time and effort to developing for the Wii U
No, just No. They make gimped versions for WiiU that make up for 1 or 2% of the total sales. Watchdogs will be no different (and watchdogs can release even if Nintendo discontinues the WiiU). Third parties couldn't care less about WiiU being on the market or not.
