What the connection between them?
Dragon vs Ryo cuz Revo Leader always defeats one of Commanders such as Kyros, Wyper and Inurashi
So only Kizaru left, I believe it represents Sun God vs Sun God, while Zoro gonna fight Magellan and Sanji vs Lucci (Sun Fight, Hell Fight, Science Fight as New Lucci is inspired from Power Rangers too)
Kizaru imo will fall before other Admirals, he won't make it to Main Event just like Cracker Fight (Actually u already theorized we are gonna have a Cracker 2.0 Fight for Luffy, I agree and believe it's Kizaru)
Kizaru, Magellan and Lucci represent returning Villains from Pre-TS and they are gonna be used to hype M3 for Final War (I'm 100% certain about Magellan Fight, 70% on Kizaru and 50% on Lucci Fight)
