I think the missing context from the post (as it calls out) is that the intended experience is that you have the diorama view at the same time as the actual footage, so it's showing you where everyone is offscreen.
When you're not "inside the action" of the live TV broadcast, you're not going to turn to a low-poly video game map because the live broadcast will give you HD wide shots better than this tabletop garbage. No one wants to swivel their head back and forth with 1.5 pounds of dork box cantilevered off their face for an experience less immersive than the live broadcast and offering zero value add.
Yeah, it seems awesome to be able to track the entire game at once instead of just focusing on what’s in camera frame. The combination of both could be very engaging.
