if you remember killer bee is dead weight and naruto was doing fine against the juubi but with sasuke and others now they could gain some grown ... i guarantee the hokages will all fight madara as a flipside to the recent hokages doom!
Minato and Kakashi vs Obito Minato will get into the dimension via the stongest plot justu in existence
Hiruzen, Taka, Orochimaru, Shinobi Alliance, Naruto, Bee vs Juubi I think this fight will take the backseat for a few chapters. Naruto main character or not has gotten too much panel time in this war and will take the backseat for a while - i want to see the Kages and Sasuke fight.
Hashirama, Tobirama and Sasuke vs Madara I was thinking of putting Sasuke with Minato and Kakashi since Obito did lie to him, but i don't think even plot jutsu is strong enough to get Sasuke there. Sasuke will against Madara because of Hashriama's story, and because Madara's an Uchiha.
I think we'll see the Senju brothers go ham, and we'll see what EMS Sasuke can really do. I'm expecting for this fight to be the main focus for several chapters. I want to see the Senju brothers go all out, and the last time Sasuke actually got a proper fight was Danzo and that was hundreds of chapters ago.
