When Pimax gets positional tracking, will that be an addon or a new headset?

Just wondering, keen on giving this headset a look but if it means I’m going to be missing out on this I can wait.

I heard it may be build into a controller… or maybe they meant the controller will come with an attachment to the headset.

Regardless, from what I understand it will be an upgrade to what you having giving a motion controller and positional tracking.
