It's unlikely the DualSense or DS4 can be tracked using the headset.
This is already confirmed, I though? Also, look at the DualSense - the LEDs have been moved to a specific place and form a unique shape on the controller, meaning the inside-out tracking via the cameras on PS5 VR's HMD would easily be able to see the size and angle of the controller, coupled with the improved internal motion tech.
