Naruto Thread (Spoilers For Sure)

Well, wether they die an resurrects or they become some sort of ghost until they materialize again isn't really important, the point is that killing the host or dispelling the edo tensei technique to make the bodies disappear could free the chakra up and Tobi would have to wait before he can complete his moon eye plan.

It is important because that time frame imbetween is the key factor. I would see the 9 tails take over naruto sooner than he would die though.
