Maybe, I guess its tough to know at this point.VR currently is very gamey. It's a theme park attraction essentially.
I don't think portables will exist for much longer, mobile is become better and better for gaming and then you have solutions like Switch as well. I don't know if VR will take over TVs though, if it doesn't get enough support it could just die off again. I think the general market isn't really that interested in it, and its a hard sell without having people actually try it.
To move past that point, I think the quality of the experience needs to be improved. The headsets need to get to the point that someone without experience can toss one on and have it adjusted properly, and then play for hours in a stationary environment without getting sick or having the experience degrade.
I don't know if manufacturers share my priorities, but the tech to have a "perfect" casual experience like that is available today. We just need it to come to market.
