Third Parties are going to have to go to the Wii U if they want their games to be sold. This thing single handedly kills the Durango. Besides Bayonetta 2 is coming out soon.
Not gonna happen. If sales collapse on the next Xbox and Playstation, publishers will simply move to other platforms like mobile, iOS and PC where there are massive user bases. Bayonetta was a great game, but it won't move hardware in the United States.
