Cool idea but will ultimately fail. Generally speaking, people don't like having to wear something. Look at 3D, one of the main turnoffs was the fact you needed to wear special glasses for it to work and I'd imagine that just like 3D this VR helmet might causes headaches/eye strain for some people. Finally, let's not forget cost! I can't imagine this being very cheap either. If released as a low volume niche thing, I could see it doing well though Well that is my 2 cents anyway, take with a grain of salt.
