Can't wait till you can buy a relatively inexpensive VR headset that doesn't need a PC or phone? You may need to wait a tad longer than we originally thought. Variety reports that the $199 Oculus Go headset will launch at Facebook's F8 developer conference on May 1. 

While that's not technically a delay, it definitely stretches the company's original promise of "early 2018."
