Seems to be a lot of launches for the VR hardware this year.

HTC have teamed up with Valve/Steam (available for pre-order)



Sony are releasing their effort for the PS4 (release October, 2016)



And of course, Oculus Rift (release March 28, 2016)

There's also cheaper alternatives, not as flexible but fun :

I got one of those last year and enjoyed it, it connects to your mobile.
