I mean your four CONFIRMED ones would be Sweeney Todd, Bad Cinderella, New York New York, and Camelot. Other than that you have only the rumored but with the crowded field, its starting to become a question of who will come in in the spring to try for awards attention in a wildly crowded field and who will wait until next season.
POTENTIALLY you could have a lot of things, but the things either with the most creditable rumors or would be most ready to arrive at this point: Broadway Vacation, Sing Street, Dancin', Lempika, Once Upon a One More Time, Devil Wears Prada, The Notebook, and then possible transfers of the West End's version of Cabaret, Encore's Parade, and Merrily We Roll Along.
