I think Nintendo is going to be the one to knock VR out of the park next year with the NX.
That's what I'm waiting for because I believe it's going to not only be a handheld device/home console in one, but also easily support the holy grail, untethered VR. With first-party support from the world's premier game developer.
Of course, it will be Nintendo art style, easier to render than faux reality. But that style is ideal for the relatively weak VR resolutions that systems have today. Personally, I prefer artistic or cartoonish graphics. If I want reality, I don't want it rendered. I'll walk outside. Go play paintball and obliterate the desktop or HMD VR experiences.
If you want to dip toes in the water and start now, I'd get yourself a Google Cardboard setup. Nintendo is going to make Oculus/Vive and the 90's VR stuff (including VirtualBoy!) look silly as they bring this to mass market. It's going to be the games, simplified setup and console pricing that will win it. There won't be anything else like it.
