I followed many fights with audio only. It was when I was flat broke and the cable was hijacked, blurry, broken and squiggly and you were lucky to distinguish a foot and...or boob at least once a minute. But the audio was great

Really though, love the old timey calls and when done right it def can be interesting. They intend to use 5 personalities all on the same call? With live shooting of the actual call-studio and no footage, obviously? That sounds like it will get real messy in a hurry but could be wrong.
