kishi does not make any new decisions...everything has already been planned out since the very beginning.
There is no need for Hashirama, Naruto will show Madara the "Will of Fire"!
agreed with this^ This is Naruto's fight. Besides, if Hashi is revived, the spotlight will be taken off Naruto and into Hashi and then when everything's done Hashi will be demanded to become Hokage again (if Tsunade's alive, she might step down) and it will kill Naruto's chances at becoming the Sixth(Seventh).
on the other hand, if the good guys will be able to extract Yamato and revive him. He might be of use in helping Naruto and the rest against the Gedo.
As much he gets brought up I hope something happens. Shoot with all the hokage. They get hyped beyond belief and we get nothing to see.(The oro fight to me dont count ciz that was wack) I hate teasing.
Personally, I feel like Kishimoto ****ed up with Hashirama. He sealed him away midway through part 1 and now at the end of part 2 he's all of a sudden an extremely important entity and is hyped to have been a ninja stronger than even Madara Uchiha, and all he's shown in action was a fraction of a fraction of that power. But at this point i think reviving him would not serve the plot very well. So Kishi has no chance of redeeming hashi without making an inappropriate plot twist.
You'll always find if only you know where to look.
Re: what if kishi decided to revive hashirama!!!
that can be fissible considering how he's being often mentioned in the mangas as of late,and also naruto have used so much chakrs fighting obito so it might totally be possible since we dont know what the creep orochimaru and the brat sasuke are up to.
