I wouldn’t get too excited. Supposedly the next headset is internally called Deckard, and it’s been “about to release” for like 3 years now? Pretty much everything people think they know about it is conjecture based off code Valve has tucked away in SteamVR; zero public statements of intent.

As for VR on Linux… kinda? I’ve only read terrible things about it online. I have an Index and tried to use it with Mint a few months back, and while it mostly worked without any configuration issues, there was a weird white ring around the edge of the screen that I couldn’t figure out.
