I really don't think that's why HTC is breaking off the Vive division. But I agree the Vive probably doesn't have a future. The HTC offshoot is currently working on a standalone headset that probably won't have anything to do with SteamVR

I doubt Valve is working on Gen 2 in cooperation with HTC, so the Vive is basically dead

Currently LG is working on a SteamVR headset that looks ok
