We do know that Valve is working on a new VR headset that will be ARM based though
is enough for most people to assume that an ARM VR headset is coming
An assumption is not knowing a fact.
It would be stupid for Valve to not at least to explore possibilities but to say that we know that Valve is working on an ARM VR headset is not truthful.
GamingOnLinux is a shitty spam blog and not a reliable source. We saw Proton-ARM and Waydroid in SteamDB and those could just be internal research that might never see the light of day. That’s it. Everything else is conjecture.
