Oculus' virtual reality ambitions extend well past standalone headsets. In a talk at Oculus Connect 5, the company's Michael Abrash updated his predictions for the future of VR headset technology. Most notably, he sees an end to the bulky headsets that define the experience today. Pancake lenses (already in use with interchangeable lens cameras) could slim down headsets or lead to ultra-wide fields of view, but the real star may be waveguide displays, where light bounces down extremely thin glass plates. You could see VR headsets that are scarcely thicker than glasses, with images that are as wide as you need. Abrash showed a concept drawing (this isn't a hint at a future product, he stressed) for a headset that would make your Rift or Go look positively ancient, although he wouldn't predict just when you might see such a device.
