It's not perfect, Valves new controller prototype is probably the closest we have to noninteusive, low latency gesture tracking with some form of feedback (the oculus Half moon prototypes were also fairly close, but iirc the gesture recognitation was neutred for what ever reason).
The definition of Retina varies based on viewing distance. The DPI needed for Retina in VR is a heck of a lot higher than what's needed for a smartphone.
IMO we need to go through at least two resolution quadruplings on the Vive to get it to be crisp enough for the screen-dooring to not be noticeable.
Also 6dof tracking with hand gesture tracking under 10ms is still a challenge. I think it's possible but needs serious hardware advancements.
I love my bridge though. No hanging cables is definitely a good thing
