I hoped Vegapunk would show up to deal with the citizens who consumed SMILES and Ryokugyu would help out with turning around the deforestation/waste caused by Kaido's factories. I guess only the later might happen, if anything.
Also, why do people assume Luffy's bounty will go over Kaido's or BMs?
I'd assume if the WG recieved notice of the alliance's (Kidd + Law + Luffy) victory, their combined bounties may surpass the combined bounties of both BM + Kaido, but it wouldn't make sense for them to attribute all/most of the bounty increase to just Luffy.
