Microsoft has recently claimed that Nintendo’s Wii U platform is “effectively a 360.” They believe that the Wii U Pro Controller’s design is based on that of the Xbox 360 controller. According to Reggie Fils-Aime however, the Wii U Pro Controller is designed for comfort.
Nintendo has stated that:
The Wii U Pro Controller is an enhanced version of the Classic Controller Pro that has been designed specially to work with the Wii U console. It simply offers another way to play and more options for developers use. We do not compare ourselves to the other consoles.”
