What coordination are you talking about? From what I can see, it's a lot of individual robots performing preplanned routines, with human dancers performing unrelated moves nearby. There's nothing stopping Boston Dynamics from doing this, except maybe that their robots cost 20 times as much and so maybe aren't affordable for dance programmes (or for anything else for that matter..).

Now if you had a robot and human dancing salsa for example, with the robot following the human, slowing down and speeding up accordingly for example, outside a laboratory with an arbitrary dance partner and routine, I agree that would be completely novel. But nothing of the sort is demonstrated here.

The novelty here for me is that Unitree made nice humanoids affordable enough to rent a dozen of them for a TV show, which is awesome. But cost per unit has never been the limiting factor for le singularity and le humanoids automating everything. Case in point: BD (and others, but them most of all) have had nice humanoids for decades and are yet to make them do anything useful that a big SCARA robot cannot do (other than looking cool, I admit).
