What is the VALVE market value?
How much did VALVE spend on development and advertising for VIVE?
What is the FACEBOOK market value?
How much was spent on the development of Oculus?
Analyze the installed bases(MS?), the market values, their proportions, then try to argue rationally and impartially.
It's obvious that all game developers are betting on the "big dogs".
We all know that VIVE and RIFT monopolize the market, but I hope in 2018 this will start to change, especially if all VR controllers adopt universal standards.
