Given how things have been going, I don't think VR will hit mainstream until the resolution (PPD) of the headsets can compete with a TV/monitor. One of the main problem with VR right now is that it cuts you off from all the 2D content out there, the resolution is too low to browse the Web and watching movies in what is essentially less than 720p isn't great either. On top of that, most VR headsets just don't work as full monitor/TV replacement to begin with, due to not having a plain old HDMI input. The software side is also severely lacking, while it's possible to bring 2D content into VR on PC, it's extremely clunky and not well supported at all. Microsoft's WMR tried to build a "Windows desktop for VR", but with that dead now, it'll take years before anybody will try that again. The lack of resolution could of course be overcome by native VR content, that is build towards the other strengths of those headset. But there just doesn't seem enough interest in the industry to actually go that route, you can still count the total amount of good AAA content for VR on one hand. That's not enough to attract gamer's in mass and in turn developers aren't all that interested either. Xbox still staying away from VR isn't helping either, as that cuts off a large chunk of the potential market too. As for motion sickness, that's a somewhat unsolvable problem. Everything that makes the virtual body move without your real body moving will make people sick, no matter how good the headset is. One solution is to not move the virtual body (teleport locomotion), but that drastically limits what games you can do in VR and has been largely abandoned again by most games. The other alternative is to just get used to it, most people can adopt to some degree, but it can take time. I think the only real solution here is a generational shift, once every kid grew up with VR, the motion sickness issue might fade away, but that'll still take many years or even decades.
