StarVR is just crazy awesome. Next iterations of OR and Vive will probably be around that, using eye tracking and foveated rendering.That thing is a beast, display wise.
I'd pay top dollar for any VR headset that could handle real time focus/depth of field as well. That's the real thing that keeps VR from looking 1 to 1 like real life.
Everything else is pretty far behind. Unless they've got another surprise.
