There are some things about Itachi's and Madara's Edo Tensei that I'm unsure about.
First Itachi...Right now he is under a very strong jutsu-the Kotoamatsukami,which was able to break Kabuto's control.Now we've seen emotion break the Edo Tensei against the user's will.Shouldn't we use reverse logic that a person revived by Edo Tensei could stay "alive" against the user's will if there is an emotion strong enough to keep the soul in the world of living.Since the crow's kotoamatsukami gave Itachi an order that was the idea of his lifetime it should create an emotion strong enough to break the bond between the jutsu user and the soul.So the question is : Will Itachi stay "alive" after the end of Edo Tensei?
Second comes Madara.When he was summoned to the battlefield it was Mu who summoned him.He didn't say "Edo Tensei" ,but "Kuchiyose No Jutsu!".Edo Tensei is a type of Kuchiyose so it is possible that the performer of the Edo Tensei was Mu.Now if it was Mu what would happen when Edo Tensei ends?Mu will disappear.But he won't "die" he is actually dead.Will that be the way to keep Madara on the table or will that bring the end of all Edo Tensei? Or did Mu only bring the coffin to the battlefield and it was Kabuto who performed the Edo Tensei.If so did Kabuto do something about Madara's Edo Tensei,along with giving him Hashirama's DNA that would make it impossible to end the jutsu even by the caster? Or will Madara on his own be able to somehow break free from the justu? He IS one mighty shinobi.He has a huge amount of chakra,EMS,Rinnegan and alot of knowledge and understanding of jutsu.
Lets hear some predictions.
Not a fanboy.No flaming please.
