Agreed. Once the cost comes down the technology will become more readily available. Gaming is a massive industry but there are other applications outside of gaming.

And don't forget the chicken-egg problem. People see it as a fad because the majority of games are smaller 'tech-demo' types, but of course very few companies will invest much money in something available to only 5% of the gaming market.

Resident Evil 7 is the exception, and my God is it an amazing experience.
