Like others have said, nobody knows. Disney leadership also probably doesn’t know for sure, even if they have internal goals. Some of this stuff requires more planning on their end, like with BBB they’ll have to re-hire and possibly hire and train new CMs for this, so it won’t be overnight. But a lot of their Covid announcements to the public have been pretty last minute, probably so they have the flexibility to reverse course in case anything changes. This whole pandemic has been unpredictable, and with the holidays coming up, I wouldn’t be surprised if they hold out on masks and other changes until after they see how the country does with any holiday surges and child vaccinations. It was pretty hard on both guests and CMs with the ping-ponging mask policy over the summer, so they might want to avoid that and wait until they feel more confident that it’ll stick if they drop masks again. Plus with the labor shortages, even when they want to reopen things like BBB, they might not be able to for a while.
In terms of advice for your trip, if those are absolute dealbreakers for you, you can always wait and see if there are changes by the first of the year. I don’t know what your travel plans entail (like nonrefundable flights), but Disney lets you cancel up to 30 days before check-in. Otherwise you might want to either do Disney another time and enjoy Universal (Hogwarts is still a castle!!), or look up the offerings at Disney that are currently available and plan some fun alternatives!
