2016 was the year that virtual reality hit the mainstream. PlayStation VR brought acceptable quality, immersive experiences to the living room, but the long-awaited consumer iteration of the Oculus Rift brought higher detail to PC gamers, as did the room-scale Vive. But all those headsets are tethered, so you're dragging a decidedly physical cable around the virtual world with you.
At CES 2017 in Las Vegas, though -- kicking off in less than a week -- HTC will reportedly show off a completely wireless Vive. With higher-res screens, to boot.
