Microsoft has confirmed over Twitter that only Xbox One controllers and accessories will be supported on the next-generation platform. The Xbox 360 controllers and accessories players already own will not work on the new platform.
"To deliver consistent, meaningful gameplay to all users, only Xbox One controllers/accessories work w/Xbox One," Microsoft said.
Microsoft also has addressed the Xbox One's Kinect requirement. In a Q&A blog post, the company said it is requiring Kinect with every Xbox One because the technology is "essential" to the next-generation platform.
"The all new Kinect is now an essential and integrated part of the platform," Microsoft said. "By having it as a consistent part of every Xbox One, game and entertainment creators can build experiences that assume the availability of voice, gesture and natural sensing, leading to unrivaled ease of use, premium experiences and interactivity for you."
