The problem with something expensive like a "VR helmet" is that few if any games would be made to support the hardware due to high costs, limited sales and subsequent limited audience.
Expensive hardware like a helmet is best played at an arcade or amusement center where the initial cost is put up by the shop rather than the individual consumer.
Future home gaming "VR tech" that is cost accessible enough for a healthy, sustainable user base, will most likely be in 3D gaming, requiring additional coding for games to utilize stereo imagery, 120hz sets to handle 2 sets of signals simultaneously, and a pair of glasses much like the ones currently being used in 3D movie theaters.
While the clunky helmets can obstruct enough of the user's vision to give the illusion of total immersion, the use of stereoscopic imagery would actually result in a more realistic experience other than that whole head turning issue (larger screen would naturally help too).
