If the next tour is something new (i.e. not another Future Past leg), the announcement will likely be after the end of the current tour. Since that is in early December, I wouldn't put it past them to move the announcement to early next year. If it's going to be another Future Past leg, it will likely be some time during the next leg - the past announcements of this type were done in early October or early November.
Either way, we're probably going to have to wait a little, so you guys have all the time in the world into hyping yourself into believing they'll play whatever song you want them to play, the less reason to believe so the better.
The Future Past Tour was announced 3 weeks before the end of the 2022 Legacy of the Beast run, I could see something being announced before the tour is over, but they might want to get the live album/video out for this tour before they begin hyping up the next.
