We're not done.
Very close, though. 2-5 chapters at most, then a bit of post arc.
I can finally post this analysis, I've been waiting for the chapter release. Let's look at how we got to Egghead:
Pre Wano-Wano:
-Reverie abolishes Warlords
-Gorosei kill Cobra, Sabo gets Cobra's D
-Wapol and Vivi escape from most secure area in world full of security cameras
Post Onigashima
1053-1057:
-Robin/Law, then Caribou learn of Pluton
-Cross Guild
-Man Marked by Flames mentioned
1059:
-Introduces Seraphim
-Koby is "Kidnapped"
1060:
-Luffy says Sabo wouldn't kill Cobra
-Luffy wants to rescue Vivi, Zoro won't allow it unless Vivi is in serious danger
-Luffy reveals his dream
-Robin talks about the Man Marked by Flames
-Lulusia incident with Uranus. Rebelling island with Revolutionary on it gets destroyed.
-Sabo flees and survives.
The wildcard here is the Man Marked by Flames, he could show up whenever Oda wants him to. Outside of that, I think we can piece together what's going to happen, because Oda really likes having arcs come full circle.
East Blue starts with Luffy going into a whirlpool, and ends with him climbing a waterfall (Reverse Mountain).
Alabasta starts with Luffy punching a giant sea mammal (whale) in the ocean, and ends with him punching a water-based reptile (Crocodile) into the sky. Arc starts with Smoker chasing, and ends with Smoker leaving and more or less becoming an ally.
Skypiea starts with a knock up stream, ends with the Straw Hats falling out of the sky.
Water 7 starts with the Straw Hats looking to fix their ship, and losing Robin because of Pluton. It ends with them burning it/getting a new ship, and a crewmate who can build a new Pluton.
Wano started with the Straw Hats going up a waterfall while separated, by the Koi fish that become dragons in mythology, and ended the arc going down the waterfall united with allies, after having defeated the dragon in question.
Egghead started with Seraphim, the Gorosei, and Uranus.
In Amazon Lily, Teach was attacked by S-Hawk, and S-Snake attacked her own allies (the Kuja), and Koby had to stop S-Hawk from destroying his own troops.
In Egghead, Saturn had his identity stolen by... Catarina Devon, who was also on Amazon Lily.
So, we'll see the Seraphim attack their own allies once Saturn orders them to kill the low-ranked Marines who saw the Gorosei transform. And, Saturn will factor into this, because S-Bear and S-Snake genetically HATE Celestial Dragons. In Amazon Lily, Koby sacrificed himself to save his crew-mates, and went with Teach. In Egghead, Kizaru will sacrifice himself to save his crew-mates, while staying on the island to hold back Saturn and the Seraphim that don't rebel.
With the Gorosei, we saw them murder Cobra, and Saturn has constantly referred to humans as "replaceable" insects, when Saturn himself is a spider, which many people would call an insect. IMO this foreshadows Saturn being replaced for his failures in Egghead. Garling would be a great replacement, IMO.
Finally, the final catalyst for Vegapunk's decision to erase his memory was Lulusia's destruction through the Mother Flame powering the Gravity Machine Uranus.
"An insane amount of energy was stolen!"
This leads me to believe Imu has more than enough charge for one Uranus shot.
This operation was well planned: the Gorosei and Marines set out at least a few days ago. If the Gorosei needed more Mother Flame from York, wouldn't they have just asked? But, they didn't. Why? They still have plenty of fuel to use Uranus.
Uranus is Imu's ultimate trump card here: but, Imu isn't stupid. Uranus was sent to Egghead once Imu realized the situation.
Imu will trust Saturn and the Seraphim to clean up the Marines that need to be killed, and secure York, the Mother Flame, and Punk Records.
And Uranus will deal with the Straw Hats and Giants.
I also expect Vivi to get captured and sent to Impel Down, soon. Imu is the highest authority in the world and requested her, but, I think the Marines are going to uncover Vivi's past ties to pirates through Smoker, and Smoker will more or less use Impel Down to hide Vivi from the World Government.
Thoughts on Smoker having the Man Marked by Flames Poneglyph, since the Man Marked by Flames is rumored to be government affiliated? Where there's smoker, there's fire?
Ayo
What if Smoker beat the Man Marked by Flames offscreen?
Finally, I'm pretty sure the other three Seraphim are supposed to attack Cross Guild at some point. Need to reread that section.
Yeah I think S-Croc, S-Gecko, and S-Flamingo are going to attack Cross Guild
