Virtual reality technologies are at a place now where they're actually fun to use, after decades of early efforts where the big dreams of VR evangelists simply couldn't quite be realized by available hardware and software. But for as good as things are today, there's a deep well of potential for them to get much, much better. One of the keys to the next evolution of VR will be the arrival of headsets with incredibly pixel-dense displays, making it that much easier for users to suspend disbelief and feel that what they're seeing is as real as they are. And now from the looks of things, Google is preparing to share just that kind of tech with us in only a few short months.
