Another big prediction...
Oh boy you know this idea I'm not so crazy about but I have this strong feeling this is exactly where the story is going so I have to post it here.
With the latest chapters we have seen all these Edo Madara super powers but you have to wonder what has been the point of showing us all of this stuff only to have Edo Madara go away. I think this is a type of foreshadowing of whats is to come later and by that I think you know what I mean....
[/sigh] Yes Sasuke is going to get Hashrima cells added to his body to enhance his power. Although it wont be the level of enhancement Edo Madara has because that is due to Kabuto's expertise as a medical ninja who has studied Hashrima's cells. Tobi also has Hashrima cells but he doesn't use mokutan jutsu's because his enhancement is of a different scale compared to the Hashrima face that Danzou & Edo Madara got.
So yeah the whole performance by Madara was to give us a rough idea of what is really possible with both powers. Sasuke's power wont be nearly as powerful as Edo Madara but perhaps a slightly lower version of the same Final Susanoo power. After all Sasuke has to go up against Naruto and the Kyuubi hes going to need a great deal of power to counter that.
Which brings us to the other part of this story which is whats in Orochimaru's super secret scroll ? Well considering Orochimaru's ultimate goal was to understand the secret of ninjutsu thus his obsession with the Sharingan. I'm going to assume its the blueprint on how to enhance the Sharingan to Rinnegan. Which will give Sasuke reason to go along with Tobi's plan but for his own reason of gaining greater power. Also given how strong Naruto is and the fact even Tobi is having trouble dealing with him means he knows Sasuke will also need a boost in order to challenge him.
There is another reason why I think this is going to happen and it is because Tobi himself mentions he wants to use Sasuke as a pawn for the GM statue. I think in order to use that statue you need to have both Uchiha + Senju powers so like it or not it may be inevitable.
To be clear just because Sasuke takes Hashrima cells does not mean he will gain the Rinnegan immediately after. Even Edo Madara didnt gain the Rinnegan until near the end of his life. I think just like activating the Sharingan & MS their is a method of awakening the Rinnegan that requires extreme emotion. The more immediate difference will probably be increased stamina and a more powerful Suanoo or well basically a boost to all of Sasuke's jutsu's. Howevere even is Sasuke does awaken the Rinnegan he probably doesn't know all its functions or wont be proficient at using it.
To be honest part of the reason I didnt want Sasuke to get these enhancements was because I thought that Naruto vs Sasuke would be based on their native abilities and any alteration would create an unbalance. However it does fit the entire theme of Uchiha focusing on power and hatred vs Will of Fire - inner strength.
Okay I'm going to take it one step further and add my speculation on Tobi. Many of us have theorized that Tobi was created by Madara perhaps using his Rinnegan and the Creation of All Things jutsu to create a separate lifeform from his own body & chakra similar to how the Rikudou Sage created the 9 Bijuu.
The harder question to answer is why?
The answer may be remarkably simple given what their plan is. Lets look at what we know and that Tobi stated himself he wanted Nagato to save his power for himself. Tobi said he wants to use Sasuke as a pawn. Edo Madara awoke and thought he was revived by Nagato.
So what was the point of creating Tobi that Madara would even risk death? The one point that keeps showing up is that a pawn is needed for snyc with Gendou Mezu!!! Which means using it comes at some risk as we have seen the results from Nagato becoming skinny. The way Tobi is using GM for battle and the process of actually recreating the 10 tails are wholly different.
In order to use GM one needs the Rinnegan which means Edo Madara must have come up with plan to use Nagato as a controllable pawn and created Tobi as his alter ego to make sure everything goes according to plan but this lead to Madara dying. Nagato was suppose to reform the 10 tails then use his remaining life force to revive Madara back to life then die from exhasution. Its one thing to just have someone with the Rinnegan but as Tobi said controlling someone means understanding how to control the darkness in their hearts and Nagato was easily influenced hence why he made a good pawn for their plans. Gathering the Bijuu was one thing but synching to GM and using its full powers was quite another and not something Madara wanted to risk knowing it would kill him.
This is ultimately the role Sasuke is taking over in Tobi's plans being the new pawn to sacrifice himself without knowing it for Madara's sake.
The idea was that once Madara is brought back Tobi may be able to re-merge with him and become complete and then they can become the 10 tails host and do their eye of the Moon plan. I have hard time seeing Tobi's body being the host of the 10 tails on its own given how flimsy it looks with arms falling off and all. So only by becoming complete can Tobi/Madara carry out their plans.
Well that's the rough idea on the upcoming revelations.
