Indeed, I always believed that Kizaru is gonna be Luffy's Next Main Fight, and it will focus on showcasing Gear 5's Ridiculous Speed
However I'm not sure if the Fight will happen on Egghead or Mary Geoise
My current Theory is that Lurking Legend will be Introduced very very soon and he will defeat Luffy & Co. Kizaru will then capture Luffy and Mary Geoise Arc starts
If next Chapters confirm some of this, I will share detailed explanation on why Zoro will definitely fight Magellan (Even though it sounds impossible)

It'd take seconds for Oda to send Zoro to Impel down if he wants to.
