There are a lot of cheaper and less bulky VR headsets coming in the near future. Wireless headsets will be the new standard.

Also more contents will come out for use with VR controller
What I think will real take VR to the next level ... feedback. You know, so you feel those smooth curves of a Jaguar and rugged exterior of a Land Rover.
VR will take the world once it becomes cheaper, and there is a lot of content to use, including marketplaces all over, as well as games, and more serious use of it, like education, date sites, movies, social games, avatar socialization, etc.
