Last Wednesday, Mark Zuckerberg stood onstage in front of nearly 3,000 people at Oculus Connect and made a promise -- he was going to get a billion people in virtual reality. To make that happen, he announced the launch of two new VR headsets -- the Oculus Go, which will be phone-free and release next year at a $199 price point; and the Santa Cruz, a wireless immersive headset that will release to developers next year and then to the wider market.
