Tsunade will most likely die, and I've kind of thought. She sacrificed too much against Madara. For the next chapter we can expect Obito's past and the reason for all this sh**. Anyways, great chapter.
So Obito is trying to bring about the end of the world all because Rin died. Sounds perfectly reasonable to me .
But I would really like an explanation on how Madara just showed up like that, I mean what happened to the Kages?
At least know two things now
Rin is dead (I am tired of all those fanfics where she is Sakura's mother and between this and Sakura's parents appearing in Road to Ninja there will finally be an end to it).
There will be no cutting away to the Kages vs. Madara fight anymore (unless it through flashback).
Finally! So, Tobi is Obito as I predicted. Chapter was nice, showing flashbacks and memories about Obito. And I'm sorry for Kakashi. Just looking on his face... Damn Obito, you bastard!
