Now that we have sub-one-dollar accelerometer circuits with enough accuracy and reliability to embed into commercial gaming controllers coupled with the existence of enough processing power to render DOOM-level graphics at the 60FPS necessary to minimize the number of people who get physically ill in the headset, the "late version" is actually very close. It has always been a hardware challenge, and we are actually likely to be right on the cusp of meeting the challenge this time. It's an exciting time to be alive.
