Most of this I can foresee. Especially those regarding Fishman Island and Alabasta. The World Government will get pissy at the mention of the Poneglyphs, and will likely come down on Shirahoshi like a stack of bricks.

While it is possible that the events of the Whole Cake Island Arc will lead to Big Mom losing control on Fishman Island, it is most likely that the island will belong to... Luffy. He declared to Big Mom herself that he'd kick Big Mom's ass and make Fishman Island his turf. This could eventually lead to the Straw Hats/Grand Fleet will end up with a few other islands as territory, such as Wano (taking it from Kaido) and most likely Raftel once they get there. Lets face it, Luffy's gonna become a Yonko the way he's going.

As for Alabasta, if Cobra talks on the Poneglyphs, while it is possible for a rebellion to start, this might end up taking place after a "Raftel Arc" ends, wherein One Piece is found. I'm expecting the series to continue even after we find Raftel and One Piece, and learn of the Void Century and such, and our favourite wearer of hats is Pirate King. The World Government is still present, and will need to be taken down, and the world itself will be at war.
