Hey, just chiming in as I noticed the PM, and thought I'd support this.
I'd be pretty happy to see it implemented about like the SRV turret. I think there's some who would like the head turret solution, but that always seemed awkward to me. Still, having the HUD glued to the screen would be nice, though I'd like to freelook I think. It's not a perfect solution, but I think it meets the basic requirements I'd have for walking around in VR on planets. Personally I'd think head turret might be awkward, as I'm not sure how you'd get 6 DOF, which is pretty important to me.
For me, options is the best solution, and I still think many of us would be fine with beta testing it before it even goes to live. I also concur with the notion that the signal lost feature could be incorporated to restrict head movement to a bounding box and still get vision.
Competitive advantage I think can only be assessed through experience. In my experience in general, countless things can theoretically give a competitive advantage, but it can sometimes have a cost in performance in other areas that simply make it less viable than a standard option - even if it's better in its niche. Now would be the best time to look at this, as if it becomes a post-release testing, you may not get much good data as mostly it's going to be the VR players wanting to play it.
