A rundown of what this all could lead to:
1) Minimum Kizaru gets defeated
2) Seraphims are probably gonna be "defeated" to get up again later thanks to York, stronger tha on before from the battle they experienced and more growm up.
3) Saturn is gonna command them overwriting the command, only Gorosei will be able to command them from that point
4) In that case alongside Kizaru, Saturn might get defeated too as that purpose can serve other Gorosei too now. York will return with the Seraphims to Holyland after the end of the incident.
5) Grand Fleet involved, as they are hyped to take part in an incident in the future
6) Dragon and the revs appear and take the fighting ending the arc shorter, but idk how far it would take for a full force of Revolutionaries to assemble on egghead to fight against that force
