What are your predictions? I'm thinking stream frame is going to be a standalone hmd, with remote computing services(either its your pc or a remote server). Able to stream any steam game available, sometimes convert flat games to 3d. maybe share/view games together with others in VR. The standalone part is probably just very basic. maybe some passthrough or small compute apps. With "apps" or overlays being a "Frame". I do hope they allow multiple "Frames" or even main applications, unlike the current steamVR/openxr implementation. Its probably a given though, since they are looking at what apple is doing.
