June 11th 9:15pm FANTASMIC! is now listed as "Private Show", so I don't think that one will be open to the public as rumored on various Disney fan boards (which probably is also the cause why it's now a "Private Show").
EDIT: My sources are telling me that this is a "Private Show" now and the only folks that will be allowed to stay after the Park closes that night at 9pm are those with FANTASMIC! Priority Seating reservations, which have long since sold out, and the media for their press premiere. Park will close that night as a "hard close" as there is also a Grad Nite scheduled that night.
