I'm expecting it to be torn down and just be an empty space for this season. I have no idea what the actual plan is, but that would be my expectation just based on what the PTB would probably want. Don't want the specter of the old FITH hanging around inviting comparisons to the new one that they are trying to show off. Plus, it's just going to be a decrepit unused major building at this point. Without use, I imagine the mold takes over pretty quick due to the dampness throughout the building. Still wonder how they kept it down all these years.
They've been busy ripping everything out this month. A lot has already made its way over to the new ride according to their social media postings and the discussions at No Coaster Con.
