It recently became known that Valve registered the Steam Frame trademark. Some have suggested that this may be somehow related to the VR direction.
Soon, dataminer SadlyItsDadley spoke out:
«Valve now has custom/ready-made drivers for the Steam Link VR USB Dongle. This will greatly simplify connecting the HMD [VR device] to your Windows/Linux PC and provide a direct wireless connection. This is Wi-Fi 6E, which supports the 6 GHz frequency».
SadlyItsDadley also said that "Valve Roy controllers are no longer marked as \"prototypes/EV1\" in the drivers".
He published the "final render" of these devices; showed what the controllers might look like in SteamVR.
