Pretty much. Also because it indicates the player when multiple controllers are connected, and it is used for signing in during facial recognition. It would suck if you had that set up and couldn't sign in because the camera couldn't see the controller. My guess is that they will allow it to be dimmed to the lowest possible amount of light needed for the camera to see it.I'm a bit confused as to why it can't be off, but I assume they want to have an indicator that the controller is on or something since there isn't any other light.
