September 7th hours (Labor Day) show the Studios extra-magic hours from 7-10, but no Fantasmic. They probably left it off the schedule since normal hours are before they'd stage the show. But do you think they'll stage it that night anyway, since there are late hours?
Unfortunately it would not expect Fantasmic to be running on that night, since the park "closes" at 7. Though EMHers will be there, it isn't going to be enough people for them to justify doing the show. But hey September is still a while away things may change. The Force willing the suits will figure out they need Fantasmic back every night by then, but, again, we shall see
