It’s not that easy really. It’s much more difficult in terms of power consumption and weight of the batteries if the hardware isn’t integrated in the headset. It adds considerable cost and weight and the higher the resolution gets the more extreme this becomes.
The weight of the battery is about 1/10 of an HDMI cable. I don't see how you get heavier headsets and higher power consumption if there is LESS hardware in it.
The HTC Vive has a wireless pack already. But it's ridiculously expensive, and I've heard of some very serious issues with it.
I think we are just a few years away from getting there.
Oculus Quest when it releases will be a lot better than the Oculus Go.
As far as I've seen the Quest is only a minor upgrade to the Go. The added tracking capabilities are irrelevant for videos. What I need is the Quest that's using a PC and has a proper resolution.
