With Wano probably ending really soon, we are about to get in the first truly new arc in a long while. The destination wasn't revealed yet, we don't know the plot, and no companions with lots of baggage and ongoing plotlines tagging along. Just the crew for a while!
What do you think this is going to be? Where are we going? What will be the main plot?
My expectation is that the next big plot will send the crew to Mary Geoise. I mean, that's not the location the log is pointing to, of course, but after a mini-arc like Jaya, they'll have to go to Mary Geoise.
It really feels like the Reverie was meant to prepare us to see this place.
My guess is that Hancock's capture will be the trigger. As her secret is revealed to the world and she's returned as property to the Celestial Dragons, Luffy will decide to rescue her.
But where is the log currently pointing to? My guess is Vira/Vila.
I think Vira is town Buggy and Shanks stayed in while Roger went to Laugh Tale. We know Vira had a fairly big city in it, and that it suffered a coup d'etat two years ago, so I guess the place is in the hands of the Revolutionaries. With Sabo's current status, I feel it will be there that the Straw Hats will get the resources to go back to the Red Line and infiltrate Mary Geoise. A small breather mini-arc that will also update us on the rest of the world much like Jaya did.
As for Mary Geoise itself, while I think Hancock will be reason we go there, it will also be the place where the Straw Hats will find Vivi again, as Imu's prisoner. And it will be where we get a lot of answers about the Void Century and the World Government's origin, through Robin, but also by Imu explaining things to Vivi.
Those are my guesses, what are yours?
Elbaf? Hachinosu/Fullalead? Sphynx? Vegapunk's lab? Somewhere else?
