I’m guessing that splitting the hardware between the face and the brick isn’t that simple and would require a lot of custom solutions.
If the headset were solely a display then it seems straightforward, but I don’t know what existing system could be used to transmit all of the various sensor data down to a brick, especially in a way that would enable quickly iterating on the sensor set. I’m not a hardware person though so if someone from hardware land could chime in on plausibility I would be curious to hear that perspective.
Once the sensor set is more locked in and/or the market is more proven I’m guessing they will go ahead and invest in a custom solution to split the face and the brick hardware.
It would for sure be an obvious win, I just think it’s probably not easy to do.
