I think March of the First Order and roaming Storm Troopers will be gone, but Jedi Training/Meeting BB-8 times will load later. I’m guessing this based on this thread:
And this one:
It seems like a lot of the HS show times don’t get loaded until about a week and a half to 2 weeks out. If you look at July 27 and 28 here, all or almost all of the meet and greets (BB-8, Olaf, Toys in TSL) are scheduled for the 27th and aren’t yet for the 28th : https://disneyworld.disney.go.com/en_CA/entertainment/hollywood-studios/
