Will there be more VR headset sales than AR headsets sales in 2025?

If you asked someone in the early 2010s about virtual reality, they'd likely hearken back to the VR craze of the 90s, which fizzled out instead of being the promised wave of the future. But since then, with the development of the Oculus Rift, Google Cardboard and other systems, virtual reality has become more accessible and more useful than ever before. Estimates of sales of VR systems in 2016 exceeded 12 million units worldwide.

Augmented reality, or AR, has come into its own in about the same timeframe. AR overlays virtual content onto images of the real world. Google Glass, introduced in 2013, and Microsoft's HoloLens, still in development, are wearable AR devices. Pokemon Go, introduced in summer 2016, demonstrated the possibilities of smartphone-based AR - no glasses needed. As Google Glass continues to find application in factories and other workplaces Apple is rumored to be designing their own AR headset. *See related question here.)
