Kuma is defeated by Saturn after putting up a fight. Luffy takes over.
Zoro vs Lucci is the only other real fight but doesn’t get much screentime.
Egghead ends with Egghead Island being annihilated off the map, Saturn’s defeat, Kizaru allowing the Strawhats to leave (maybe dying in the process), the Blackbeard Pirates get York, the Mother Flame or both.
Kuma gets restored (either briefly for a tragic goodbye, or permanently).
Cross Guild make a big move, potentially the second big ID breakout so they can bolster their forces. Moria also joins Cross Guild.
The fight from the Jump Festa message isn’t Shanks vs Blackbeard.
Blackbeard is busy travelling to Mariejois with Garp as a captive.
The Jump Festa message may mean that their’s some funny business on the way to Elbaf that delays the arc. Maybe Kuma using his fruit to launch the Sunny (and everyone on it) to another island first.
Dragon will tell us he’s about to make a move (again) after the events on Egghead but it will be years before he actually does.
We see Imu before the anime gets to their voice. The anime will get there in ~23 weeks at the earliest (although probably longer, the anime will take more recap breaks I imagine.) Oda’s likely got about 18 chapters to get to that stage, which is do able with Egghead being at the stage it is and Saturn in the spotlight.
