The problem with stand-out tech like this in the gaming industry is that developers aren't going to make their games just to accommodate this one standout system when they could create a game which will work on every console equally, instead, and forgo the controller's tech entirely. The only games we'll ever see use the Nintendo Wii-U's tech, will be games made by Nintendo.
