TL;DR: Valve launched the Steam Frame VR headset with an Arm-based Snapdragon chip, aiming to run Half-Life: Alyx natively and streamed from PC. The new hardware features a “Frame Verified” status for optimized games, while rumors suggest two upcoming Half-Life titles supporting PC and VR cooperative play.
The ltt vid said that valve were not going to produce the index hardware anymore. So probably not. But they were open to someone else taking on the index if they wanted.
