At Oculus Connect today, Facebook CEO Mark Zuckerberg announced the company's next headset: The Oculus Quest. The big selling point is that it's a completely wireless, 6DOF all-in-one system—it doesn't even have external sensors—but still offers "Rift-quality experiences," according to Zuckerberg. So it's a much-improved Oculus Go, basically.

The "Insight" tracking system, which allows it to operate without external sensors, is powered by a gyroscope, accelerometer, and four on-headset sensors which build a 3D map of the room.
