Er, how does this work in a stadium? Some stadium concerts already have premium prices for the area closer to the stage, but the others can at least see the same thing, albeit from further away. If the "donut hole" is the premium area, what do the people outside the donut get to see? Guess I'll have to wait for a video of this. But this whole "360° stage" thing smacks of "using the stadium capacity as efficiently as possible to make moar money"...
