i agree that sasuke will , he will push his EMS into rinnegan , and naruto shows more signs of actually being rikudo sennins reincarnation , i mean , KM has his markings , tons of chakra , befriending beasts and potential for rinnegan , i think its a paradox in a way if they both have rinnegan its immovable object(sasuke) vs unstoppable force(naruto)
