Hi you guys!
I'm under the impression that to attain peace the whole Akatsuki organization and Obito/Masked man was necessary as bringing war has brought all shinobi together. We just need Obito and Madara to stop the project "tsuka no me" BS and peace has been achieved.
Something to think...
Now I know a few chapters back Sasuke unlocked EMS and gained significant power but could Sasuke be heading to the snake sage temple to become a sage himself?
