I think Children of a Lesser God is the only show that is on the cusp. Both Spongebob and Once on this Island will get a fair number of nominations, including Best Musical/Revival. Margaritaville won't, but the producers will probably keep it open long enough to have a number on the broadcast.
Children is in a trickier situation. The Best Revival nominees will be Angels in America, Three Tall Women, Travesties, The Iceman Cometh, and ... something else. When there were originally only 4 nominees, I would say that Children had no chance, but with five, it has a shot. It will get a nomination for Lauren Ridloff but probably not a whole lot of other nominations.
If Children does not get a Best Revival nomination, it will probably close.
