Facebook’s developer conference gets underway on April 30 starting with a keynote at 10 am Pacific.

This is a time you should probably mark on your calendar for major VR and AR updates. We expect announcements related to Oculus Quest and Rift S. The two new VR headsets from Facebook are slated to launch this “spring” for $400 each, though Quest is a completely self-contained system while Rift S requires a costly PC to operate.

There is apparently no keynote on the second day of the F8 developer conference. This makes it very likely we’ll get major updates on the company’s VR and AR efforts during the April 30 keynote. You can check out the full schedule here. Below are some of the VR and AR sessions which will be held during the event.

All times are Pacific:
