1) Is Sasuke going to try to bring back the hokage(s) as they were the only kages not summoned primarily because they were sealed? But being sealed and being revived has been and can be broken just as Orochimaru did. Hashirama could be revived in a similar way as they're are 100,000 bodies with his DNA. Madara kept telling the 5 kages that only Hashirama could defeat him. Is he foreshadowing Hashirama's return? Idk .
No, Orochimaru was never sealed. Hashirama, Tobirama, Minato, and even Hiruzen were all sealed, so they can't come back.
1 1/2) Everyone's attention is on Naruto's battle but I'm siked to know how kishi will balance Sasuke's power to Naruto's. If Sasuke gets another upgrade it will have been so soon. We don't even know his EMS's true power. Will he get the Rinnegan? Will he get Perfect Susanoo? Or both? Sasuke is playing Underdog here and will be a big factor towards this battle.
I'm betting that Sasuke and Orochimaru won't make another appearance before the war (and the manga) is over.
2) Where's Naruto? This question has nothing leading to it or out of it. He's fighting Obito one moment then gone. Possibly to go help out the kages after seeing Madara's appearence. Or maybe he isn't even gone.Who knows. It's a true mystery until Kishi tells us.
He's been fighting on fumes for the last 50 chapters. My bet is he's sitting in Sage mode gathering Chakara to keep going. He wouldn't leave the battlefield with Tobi and now Madara as opponents.
3) Who's this Uchiha Gaeshi and Kaenjin? Is it that man that you see at the last page? Obito and Madara both said an Uchiha name as they fought. Did one of the two Gaeshi or Kaenjin work as a third party to give information between Obito and Madara? Is that how they know each other so well?
If you read the manga, it tells you that it's the name of a technique, specifically the blocking/reflection ability he used with his fan.
4) How did Obito become so strong? So intelligent? He was haste and reckless . Kinda mirrors Naruto's early ages and falls out to be like Naruto in the end. The bad version of Naruto. They both started weak and ended strong. Kamui is part of reason why but they're is more to it.
Most likely with lots of training and instruction by Madara himself, just like Naruto with Jiraya, and Sasuke with Orochimaru.
5) What side will Sasuke be on when him and Orochimaru show up at the battle scene? Sasuke did have a goal to kill Naruto before his encounter with Itachi. But maybe Itachi changed Sasuke mind. How i predict it to be is Obito vs Gai, Kakashi, Suigestu, Jugo and Madara vs Naruto, Sasuke, and Orochimaru, thats IF they decide to be on the Shinobi's side Kages should sit this out if they manage to survive.
Like I said before, I'm pretty sure that Sasuke is done for this part of the Manga. He was originally looking to get revenge on Konoha and it's leadership for the death of his entire clan, particularly his mother, father, and brother. Now he's looking for the truth behind everything. I don't see his new goals having anything to do with the rest of this battle.
6) Let's not forget the one's who helped Naruto defeat Pain. Will Ma and Pa join the battle along sides Gamaken and Gamahiro and Gamabunta? He's far past the sage state as in power-wise but a little support against Madara wouldn't hurt.
I don't think any of the frog sages are any match for Madara or Tobi at this point. Naruto is leaps and bounds stronger than he was against Pain, I doubt the frogs would be very useful or helpful.
7) What are Obito's true Motives? Is obito under Madara's controll as he is capable of doing? Or is Obito on Madara's side simply because he agrees on terms what he wants to do and because he saved his life possibly? Doesn't seem like Obito runs this show anymore since Madara's appearence?
Obito has stated his true motives several times, to complete his Tsuki no Mei plan and enslave the world. We don't know yet if that's Madara's plan, so that's probably the better question: What is Madara's original plan, and does it align with Tobi's?
