I know I've already posted a few times on this thread, but I've realized that I haven't actually stated my opinion yet. Great chapter, 5/5. Definitely gonna influence the outcome of the war, whether the Hokages go to battle or not. Even if they don't they still are going to answer all of Sasuke's questions which will (most likely) change his position. Worst case scenario: Kages don't go to battle, Sasuke turns good. Best case scenario: Kages go to battle and get some tag team action up on Madara and Tobi (possibly even convince Tobi to go good?). If this happens, total sentimental stuff between Naruto/Minato is gonna go down, old rivals Madara/Hishirama meet again, etc. Best case scenario (extended): Orochimaru turns the Kages against the allied shinobi forces, Naruto and Minato fight it out, Shinobi Forces fight Hiruzen and tobirama, Sasuke fights Orochimaru, and the rest of the old kages (that were originally fighting Madara) come back and fight it out with Hishirama.
Either way, whether this all happens, or my prediction doesn't even come close, get ready; tons of flashbacks and talk scenes headin' our way.
