Gypsy, Into the Woods, Crazy for You, Forum, Cats, Les Miserables, Beauty and the Beast, Miss Saigon and City of Angels all seem very likely. I wouldn't be shocked if A Little Night Music became the Gypsy for celebrities with such low vocal demand and the fact both actresses who played it have won Tony Awards.
I'd love love love a Carousel or Secret Garden revival, but I don't think either one is too realistic.
I agree with the usual - Gypsy, Sweeney, etc, but I've always said Hairspray will be revived some day - start off as an Encores or City Center thing and work it's way back to Broadway.
I'm sure Funny Girl will eventually happen, so there's that as well.
