A thought occurs, could we potentially see the attraction open earlier than 2019? It could be a simpler job, as I think
@Andy mentioned that they would be doing a Guardians approach for the attraction itself. And that I doubt that the Chinese Theater will leave, so they could easily get this ready by late summer 2018 if they pushed it fast enough.
Just a thought, but I wouldn't be surprised that this thing goes for early spring 2019 instead.
