They just need to make a dedicated VR console with everything built in and an updated headset included to go along side they're main console. No rush but I hope it happens cause VR is THE SHIT. If they can do this for under 500...or hopefully closer to 400 once VR has spread a little more into the mainstream in the next 2 or three years, I think they could sell 10s of millions of them.
I'm sure the PS5 will be built to be VR ready, with the only extra purchase being the headset itself ($200 max). I wouldn't be surprised if the DS5 plays double duty; a traditional looking gamepad that splits apart and has built in motion tracking for VR.
