Uh-oh, you forgot [title of show]!
I think a load of play revivals with names does sound quite likely. Plays don't have to be so set-happy as musicals (I know musicals don't have to be set-happy either, but Broadway audiences seem to like it if they are :P) and don't want choreography or so much music.
I wonder if there might suddenly be a surge of productions of right-free works? G&S, Shakespeare, Greek stuff, etc...
