Oculus is greatly slowing down pc vr headset development and yes will develop rift 2 but over a longer period of time than originally planned. Why? Because of 5 g. That will take time since interstructure and everyone adopting it takes time.
But make no mistake it's coming and will change everything. Pc vr where you need bigger and better graphics cards etc.will come to an end. 5g will support stand alone headsets with the power made of dreams. 5g articles are all over Internet. Check it out and you may agree with me.
