Yea man great prediction. Only thing I would change is who sasuke fights 1st, I would much rather see Sasuke vs Kabuto... or Sasuke vs Naruto.
Remember Sasuke told naruto he will kill him first, which means he will go searching for naruto. Only thing I hate is the fact that sasuke will lose this time to naruto.
Sasuke is strong, but naruto is becoming a real sage of 6paths.. sasuke won't be able to kill or beat naruto up... lol he will be lucky if he survives like madara did against the 1st.
also he said he would kill naruto first by heading to kanoa or however u spell it he still will participate in the war and im sure he wants to kill very kage and my predictions of the next kage are
the 7th Hokage: Shikaku Nara or Kakashi Hatake i think more Shikaku because he is great in planning the only badthing is he isnt that strong kakashi has the mangekyou
the 6th Mizukage: Ao because he is strong and has the Biakugan
The 6th Kazekage: Kankuro but i highly dought Gaara will die
the 4th Tsuchikage: Kitsuchi son of the 3rd Tsuchikage 2nd company captain which is the close range battle unit
The 5th Raikage: Darui one he is a great planner two he has learned the "black lightning" and he is the 4th raikage's other arm
The 5th Hokage will die by sasuke when pretecting naruto who is already injured from a fight with sasuke The 5th mizukage by sasuke in a few chapters the 3rd tsuchikage old age and ran out of chakra the 4th raikage killed by sasuke by fighting him
i think sasuke will discover the next lewvel of chidori : Chidori -> Thunderclap/kirin (used against itachi) -> ???????
and naruto will discover the 3rd level ofrasengan after rasen shurikan
