we cant know yet but lets assume (and hope) the kages are going to the battlefield or there will be a different sort of interaction between the kages and naruto. now i wonder, is this edo minato linked with the one who showed up when naruto fought pain? it cant be because it was chakra he seperated from himself and sealed into naruto but on the other hand i dont think kishi is going to repeat a "first" meeting. what do you think?
