I do know that when there were rumors of Dirty Dancing coming to Broadway after the tour that it was looking at the Neil Simon. I also know that around that time the rumors were that Love Never Dies was aiming for an opening of fall of this year on Broadway rather then fall of next year on Broadway. So, it's hard to say.
As of right now that theatre is off the table as an option due to the fact that Ragtime going to start previews soon. And, as far as I know, it's an open ended run. So, there is a chance that it would prevent the Neil Simon being an option for Love Never Dies.
I would think that considering the great relationship Really Useful has with the Shuberts, that it would opt for a Shubert house. But, I don't know. I can see it play The Broadway but as of right now I do think that it is really hard to say where it is going to be going.
