Question

[Funnyg0]

Madara said that he wanted to be revived through the Rinne Tensei. But if that happens, wouldn´t he return as a old man again? so whats the point? ...

 

[Sage of Nature Creation]

Good point.

 

[Takeshi Uzumaki]

Think that's why obito will die using rinne tensei on madara...to take him back to him prime....remember nangato revived a whole viallge (as they were at the time of death) but he could do that maybe die to uzuamki bloodline (strong life force)

 

[zinescience]

maybe u can be made young 2ru rinne tensei.

 

[thegame]

Well, yeah, but sealing the juubi could change that.

There are also other possibilities, perhaps he knows a way to bring himself back in a younger form. You never really know, when it comes to Madara.

 

[Sir Blades]

could be a possibility.

 

[Frikid]

nagato couldn't revive jiraiya because "ït was too late"
how would nagato have revived madara then?
further more, How would obito revive madara ?

Either jiraiya never died or it is a plot hole.

Answer to your question :
idk... even i have been thinking that for sometime and couldn't come up with a logical explanation.

In order to become the Juubi's jinchuriki Madara needs to be alive.

 

[AruukoKyronn]

even for revival of the dead there are limitation as to how far back you can revive someones age but in naruto things that seem impossible have been made possible thats fine by all point of perspective but i honestly think madara will not be revived to his desired age if he is even revived because of obito giving him attitude about it basiclly madaras being used as a control for juubis power but if madara or obito are killed madara is out of luck with any option to be fully revived period
