As much as I like VR I have to agree it will stay a niche product. The need to wear something on your head is a major hurdle. Like 3D TV's that have mostly disappeared. Also when you are in a VR environment you want to interact with it. You need free physical space to do that which is an other hurdle. There are more niches than gaming only though. Like education and product design and demonstration.
The main problem with 3D tv was the content. 3D really only works with bad movies like resident evil. You are not going to have need or want 3d in a movie that is an oscar contender. (Avatar as the single exception)
Did you see the Great Gatsby? Did you see it in 3D? It was almost like the sober examination of the unrestrained materialism and absent moral center of the roaring 20s jumped right out at you.
