I could of sworn I read an article about 1-month ago that WDW has filed a large number of construction permits for refurbishments/construction. My understanding (and it has been years since I attended Fantasmic) is that the theater might be in need of repair and maintenance and that the work would be long overdue. I wouldn't anticipate any show returning until next year sometime. Plus, as the PPs have noted, they need to rehire and train CMs.
