Oculus Rift held an Oculus Connect conference in Los Angeles yesterday, unveiling a new virtual reality headset prototype dubbed "Crescent Bay," because codenames. Ars Technica has details on the new units, which include improved optics, higher resolution, a higher refresh rate, and 360 degree head tracking (keeping our dreams of an exorcism simulation alive). Also, this trailer shows off John Carmack's keynote address at the gathering, where the Oculus VR CTO fills us in on the state of their virtual reality headsets and video gaming in general. The clip runs over 90 minutes, and will leave you with an undeniable nostalgia for cargo pants.
