Not really. Last time we saw Oro and Sasuke leaving for "the one who knows everything" was about 15-20 chapters ago.
Sasuke could join the battle at the very last moment and safe Naruto from a finishing blow from Madara/Obito (to make it crystal clear on which side of the war he is), followed by a 2-3 chapter flashback explaining why Sasuke is now on Naruto´s side (the talk between him and the one who knows everything).
People are saying why should Sasuke help them but please come on, its clear that Madara had a big part in the Uchiha massacre. Most likely because of the reason that p0002q stated. And Sasuke will try to take revenge for that.
BudakPurba and p0002q are the only realistic one´s in here.
Madara+Obito+Incomplete Juubi were already way out of Naruto´s class, no way in hell he´s beating now a even further improved Juubi.
tq Fluffyman for agree with me..
Who is the man so called " mr know everything"?
i bet he is someone who is old and lives for ages/ had lives in a few kages era.. maybe the konoha elders.. but i'm guessing oro means Madara.. sasuke and oro already knows that madara is already revive.. and he might has a few knowledge / tricks under his sleeve..
and for others.. try to consider this.. now, Madara is not fighting his heart content/ all out.. he seems like playing and toying Naruto and his companions ... he might had fight seriously during his last battle with the 5 kages.. he uses susanoo, he also uses his wood clone + susanoo.. but when fighting naruto.. he just uses medium tech.. and with juubi awakens.. it seems hopeless for SA.. even shikaku has think of a strategy.. it might works.. but the capability to act the planned is impossible.. normal attacks is not works / injured any bijuu.. large number of shinobi also didn't helps..
10 tails is mostly like an uchiha in bijuu mode.. see his eyes is full of tomeo .. an uchiha only posses 3 tomeo and can do so much damage to his opponents.. what will 10 tails eyes did? a massive genjutsu.. another version of susanoo.. another version of amaterasu.. we didn't know yet.. its was important so that madara is waiting for it to fully revive..
what i'm saying is.. if 10 tails eyes are as uchiha eyes.. so the rest shinobi is useless.. naruto also will be useless.. thats why is said only an uchiha is capable to defeat Madara & tobi & 10 tails... sharingan must be counter with sharingan.. ok, ino body switching techs is maybe crucial.. maybe she can slip into juubi mind and turn it agains Madara & obito.. but, Madara will counter it back with sharingan, and control ino back.. so at last juubi is in Madara hand..
