I think what's most likely is one of those limited run Christmas shows- Elf, A Christmas Story, etc. coming back first.
But musicals I think will become classics and get revived eventually- Once, Fun Home, Gentleman's Guide, An American in Paris. The others that will become classics- DEH, Hamilton, TBV aren't going away anytime soon.
I won't be surprised if the most recent revival of Les Mis comes back either for a limited run.
