Circus show aside as well as obligatory world star-gazing at Nika, I guess this a fast track to Elbaf now that Giant Warriors are here.
I wondered if Elbaf was coming before Mariejois or after and always leaned towards after MJ but I guess Giant country's backing will be necessary in the great war after all... Considering how many allies that is, CoC crowd control will neg 90% of them because no way WG can match Alabasta+Dressrosa+Fishmen Island+Wano+Elbaf+SH and Grand Fleet+Revolutionary Army...
So, the great incident that shook the world on Egghead can be the complete annihilation of WG and Marine forces, as expected.
The only question is who beats Kizaru and who beats Saturn...
I am still betting on Zoro 1-hit KOing Kizaru and retiring him for good while Luffy beats Saturn with Ancient Robot and Blackbeard Pirates end up taking him hostage which is a fast lane towards MJ and Blackbeard's coronation ceremony.
