Hilariously almost all my Apple TV's are mounted to walls behind screens, so as neat as the far-field mics are, I can't see them working terribly well when they're behind the TV.
Anyway I'm happy with my current units. If I was outfitting a new living room I could see this new one, but for the time being I'm not rushing out.
My (single) Homepod Mini reacts to voice commands from any room in my 86 square meter apartment. When the doors are open, I can talk to it basically through the wall, without raising my voice.
Do not underestimate modern audio technology.
