1. I believe Naruto's next power up will be the Yin chakra which will hopefully give him access to more power and merger of sage+Bm.
2.Naruto will be Hokage and then Sasuke will..It would be pointless after 10 years of Kishimoto writing Naruto always saying "I'm going to be Hokage" " my dream is to be Hokage and be acknowledge by everyone" the whole story would be ruined if it turned out that after 3 years of Sasuke doing wrong and finally being enlightened by Itachi now he wants to be Hokage..After Naruto trained so hard and over came adversity & bigotry to jus step aside to let Sasuke become Hokage..I think this is jus to set up the battle for title of Hokage between Naruto and Sasuke..It's a good twist to put that fight in action even if it's a non lethal fight.They both love the village and want to protect it..I think once Naruto wins both will work together to protect the village not like Madara and Hashirama did..This will be the total opposite of that.(I hope Kishimoto doesn't f this up)
3. I'm hoping he's healing Tsuande and the other Kages
good review
