As is the case with many Microsoft announcements, the new Xbox One S console leaked before the company had the chance to confirm it at its E3 keynote. Now that it's official, we know that it will come with 4K and HDR support, a 2TB hard drive and front-facing USB port for that rarely-used Kinect accessory (if you buy an adaptor). Oh, and it's 40 percent smaller than its predecessor and has an integrated power supply, ditching that clumsy power brick. But how much will it cost?
