Will NBC fold and fire Fallon and Meyers and, if so, when?

As I noted in another thread on the Fallon situation: only the very biggest stars have any leverage whatsoever.

Edit: as was often discussed during the recent SAG strike: the vast majority of SAG actors aren’t working at any given time, and only something like 2% of SAG members are able to make a living solely by acting. Actors who decide to strike over this will likely replaced by actors willing to cross the picket line.
