A quick look at the streaming function of the GO. This is much more of what I personally think all VR headsets will be like in the future. You have your massively crazy PC pushing data as a wireless stream to your headset. Your mobile VR device simply sends back a stream of positional data.
Now, Steam in-home streaming has go a huge headstart - but anyone could win this race. As is now, streaming only works for 2D data, so basically flat screen mirroring of your PC or Xbox.
