Check out this new industry development called The International Future Computing Association (TIFCA).  Future computing is the practice of turning dreams into reality with computer technology and media and is made up of three pillars that include computer technology and peripherals, immersive technology, and innovative content and applications.

Interesting announcement from Valve, though we are left with more questions than answers.

There are two ways to enhance the perceived image quality of your VR experience.  The first is to get your computer to deliver the native resolution of your HMD.  Depending on your platform, it currently starts at about 2160 X 1200 pixels and goes up from there.  While an increase in hardware pixels combined with an equal amount of rendered pixels is the ideal option, it's limited to the number of physical pixels on the display and your computers ability to drive them.

The second method is to use a supersampling technique whereby your computer sends extra pixels and smooths things out even though your hardware has a physical limit on what it can display.  It's expensive from a processing point of view, but it delivers a significant improvement if your graphics hardware can handle it.
