I don't really believe VR is going to be much anything in the near future, simply because it sucks. Well, at least with the modern solutions. Few years back I tried one of those VR helmets to play some Hexen 2 or something... it was horrible. Not to mention the lowly res (all scalable to modern day stuff), the weight of the thing and the fact that it had kinda low Hz rate which made it more TV style. That equals Headache.
For full VR solutions, you'd need somekind of platform where you could move. (inside a sphere, perhaps?) So it's gonna take lot of space and it's much more complicated than just playing on a computer or a console.
I can't remember what it was called, but the half-vr method might work. Picture your household represented in accurate 3d model (that's gonna be a problem) and then wearing simple glasses that overlay the game gfx over the normal view. Properly done, it could be really immersive, but also something different from normal gaming. I could see halls built for this kind of stuff... like a themed places where you could go to play.
They already have some working applications for this. One that I'm aware of is this city-tour guide. or whatever you want to call it. Basically you have glasses on you and it displays info on whatever you're lookin at... or perhaps a minimap. Just for the other side, though... It also has pretty accurate GPS system so it can provide all the right info and so on..
