I assume eventually there will be an upsell product that allows you to watch with a 3D/VR courtside view. I’m kind of surprised it doesn’t exist already. I think Apple would sell a few more headsets if they made this happen.
In addition, the real end-goal would be complete 3D reconstruction that lets you view the stadium from any angle, but I imagine that's a few years away still - lots of technical problems to solve to create a scene and stream it in real-time.
