Guys please read this and let me no your thoughts, no bashing please... the only thing now is that Naruto shippuden is getting even more interesting and twisted; we dont know who is on who's side so it is difficult to clearly predict most events to come. However here are the things that we know currently:
1. Orochimaru has taken over zetsu as his new host... what does that mean, I hear you asking? Here is what it means for the manga:
a) Orochimaru now has his full power back
b) He now has his hand signs back, so he can now weave signs and use his own jutsus as he previously could before his hands were taken plus you would all agree with me that he has a whole arsenal of jutsus including forbidden techniques that he learnt when he was in Konaha plus the new ones he has researched so far.
c) If he wants Sasuke's body he could actually get it for real this time because he is at his full power and potential, even more than that; he now has Zetsu's powers (Hashirama's cells) which makes him stronger than before because he can now use the wood techniques, sensory type techniques, slipping through objects from the ground, massive clone ability, stealing/collecting chakra from other, chakra distribution and having done a lot of research on Hashirama and his cells, Orochimaru must know some other techniques that are hidden from people.
I wonder if he will have power over the other zetsus though like controlling them and having the work for him or is it going to just be the one he absorbed or went into?
d) He has the 4 previous hokages which are amongst the strongest shinobis in the Naruto verse, and since he has collected Kabuto's knowledge as well, that means his Edo tensei is even stronger and the binding is even toucher than normal and he can let them do as they even please in battle i.e not controlling their techniques and allowing them to use their powers as in the case of how they would have used their techniques when they were alive.
However we do not know why they (Sasuke and his boyz) are allowing Orochimaru gain his power back
2) For Kurama and Naruto: Kurama should have the other half of his chakra back, since the death God's belly was opened although I dont know if the chakra is in its belly or in Minato, but anyway now that would mean that Naruto-Kurama mode will even get stronger, may be they might have new abilities together which will be brought out by the other side of Kurama's chakra and also he will get bigger once more as in the old days. Therefore, upgrades are coming in every direction
3) For Sasuke: I dont know what he is planning to do at all, he is still caught up in the decision of whether or not he wants to destroy the leaf, although in the new manga it was shown that he went up the building top to soak in his decision, but I personally think that it is a sign of weakness and it will make him change his mind in the end ( as long as there is a little bit of remus in his heart, the will to do it can be altered. If he has to do it then he shouldn't even be soaking anything up; therefore I see a change of mind/heart coming later.
This is mainly because when you take a careful look at Sasuke, it can be observed that he is seen to be on the bad side but all he has done in life after exiting the village has been to fight evil and take revenge on people that needed to be wiped in order for the world to be a cleaner place e.g. Old Orochimaru (he had to defend himself in other not to get absorbed and also to absorb Orochimaru to get stronger in order to wipe Itachi who killed the clan as a penalty for his act); Itachi (already said); Danzo (he deserved to die for his old and unchanging evil ways). How ever you look at it, he had to do all these things in order to develop, satisfy his conscience and also grow stronger as a character, because he wouldn't have gotten as strong and exposed as this, if he was still in team 7 (even though I don't like the fact that he left).
Another hypothesis that I am not really sure of is; if the 6 zetsus in him would have had any impact like releasing some senju chakra in him.... In that case if it happened to be true, then the null hypothesis of Zetsu just being there to monitor him is untrue and would be rejected. Therefore later in the manga Sasuke might actually get the Rennigan because of this event that took place without realising it, or he might get his hands on Hashi's DNA somehow.
4) One thing we don't know is who's side Sasuke and his team are going to be on. Currently I think they might be on Obito and Madara's side especially Orochimaru. However I dont know the case for Sasuke but for sure he might go with Orchimaru because they might be trying to get their hands on Juubi or the power left after Juubi is taken care of, then and only then can we see Naruto vs Sasuke part 2, which wont be really fair on Naruto because he has gone from training straight into war; fighting the tailed beast, Obito, then Madara, and the Juubi. So their fight wont be on level ground but I think he will still beat it into Sasuke's head and bring him back then he will finally end the war together on the same team.
I think Naruto would have to fight his father (That is why Kishi actually took time out to make Naruto surpass his Father in his techniques apart from FTG and Sealing even though he used the Rikudou's seal on Kurama after taking his chakra), also Naruto will have to surpass the other previous HoKages as he has always said that "I will not fail till I become Hokage and I will surpass all the others before me" I believe he will surpass them and reign supreme as a boss. On the Plus side we will get to see how strong the previous Hokages are because people have always asked; who is the stronger Hokage? or they argue about the hidden Techniques that each Kage possesses just because Kishi hasn't shown us all their techniques, so here is our opportunity to see most of their advantageous techniques and fighting styles (e.g 1st Hokages other techniques, all the jutsus known by the 3rd hokage, 2nd Hokage's arsenal and his S/T jutsu, water style and bringer of darkness and see the difference from that of the 4th hokage and see the 4th use sage mode and other justus apart from sealing, FTG and rasengan which has already been spammed too much)
In all this, remember that Naruto and Sasuke can stop this war because they are the 2 potential people that are very strong currently and they can form a 2 man team that cant be broken because Sasuke has EMS with the jutsu that come with it and he can stop the Edo tensei now, after watching Itachi with the sharingan make Kabuto to weave the signs,and now he know Izanami and Izanagi as well in the worst case. Naruto has Kurama and all other advantages from making clones and having them use different techniques plus Kurama having the other side of his Chakra now that Death God's belly is opened or is the other chakra in Minato instead of the death God? in that case Naruto will surpass him and he will release the chakra to Kurama as a farewell package lol
