"Sony took the lead, shipping more than 490,000 PlayStation VR (PS VR) sets in Q3. It was followed by Oculus, which shipped 210,000 of its Rift headsets. HTC took third place, shipping 160,000 Vive VR units. Collectively, Sony, Oculus and HTC made up 86% of the total market in Q3 2017."
This doesn't include mobile vr sales that are obviously much bigger.
Anyway Sony dominating the high end market.
