— If the World Government takes control of Wano, it would be just Orochi 2.0 (the Government wants all the weapons, fabrics, and secrets of Wano. That’s what the CP0 were negotiating with Orochi early) and given the history that Wano closed itself to not be under the old World Government, I don’t know why they would open their borders now to join the World Government. I think the whole purpose to open Wano is to help the next Joy Boy.
— It’s been a long time since we’ve had a Big Party like the ones of Skypiea, Water 7 and Fishman Island. Luffy said they would commemorate the joining of Jinbe together with everyone after beating Kaido.
— Zoro said he’d like to pay his respect and go to the shrine of Ryuma, so this would have to be after him recover of the damage he’ll have as soon as the effects of the drug wears off.
— Robin still needs to find the Poneglyphs located in Wano.
— We’ll see Momonosuke taking his place as the new Shogun.
After the party, we’ll learn what happened at the Reverie through Leo and Sai, as they were there and must know about Vivi, Cobra and Sabo.
Leaving Wano, now with Wano’s borders opened, one of the wishes of Oden, Yamato will go with the crew, as she said to Luffy that he should take her with him. So she’ll sail through the world and write in her journal like Oden did.
Tama will stay as she’s not a kunoichi yet, she’ll train under Shinobu, and the main reason being that now, she’s one of the most important people responsible for the protection and rebuild of Wano. She controls all the Smile users of the Kaido’s crew, now her underlings. She can’t leave Wano so early.
And with this, Wano would be over.
