On Thursday, Sony announced that it has sold over 3 million PlayStation VR systems. While that's an impressive feat, it gives us an indication that virtual reality (still) hasn't really hit the mainstream.

Sony has sold over 82 million PlayStation 4 consoles. So the 3 million statistic means that only a small number of PS4 gamers are opting for VR.
