I'm honestly wondering how the next couple months will play out, since with us only being 9 days ahead, but assuming they'll still want to have the 2nd anniversary stuff coincide with AX weekend, there's going to have to be some kind of shuffling somewhere. The JP schedule, looking ahead from Hunting Quest 3, was this:
Hunting Quest (1 week)
Rashomon rerun (1 week)
dead week (1 week)
Onigashima rerun (2 weeks)
Agartha released (2 weeks of free time afterward)
Summer rerun (2.5 weeks)
Anniversary (1.5 weeks, including the Bunyan mini-event)
which, if we follow it with no changes, puts us at just starting the Summer rerun heading into AX weekend, and I don't think they would just stack all the anniversary things on top of that. I guess the simplest solution is just swapping the anniversary and summer rerun, but I don't think FGO NA has ever outright changed the order of events/campaigns like that before.
