MS vs MS. Now at last for the first time, we'll see a mangekyou sharingan vs another mangekyou sharingan. Dialogue winner -- Kakashi (to Sasuke): Why do you blame Konoha for Itachi's death, you killed him remember? This should be a good counter for that smart-ass rejoinder -- Sasuke (to Itachi's 'I don't want to kill you'): You say it like you actually could! Of course, this refers to both Kakashi's skill and nature (I now understand the Sandaime when he fought Orochimaru, he still loved him even as he needed to kill him).
I hope Madara's words are true about Sasuke's condition. because if it is, then Kakashi will sure kick Sasuke's dark ass, and then end his eyesight if not his folly or his life altogether. This time, we'll see how Kakashi has developed his MS since the last time we've seen him. We've seen Sasuke and Danzo show their formidable jutsus, now it's Kakashi's turn. And I don't think Kishi 'resurrected' Kakashi from being killed by Pain only to die again in the filthy hands of Sasuke. This is Kakashi's time to step up and be the Hokage...
Sasuke > Kakashi? Even if Sasuke proves to be stronger and would actually gain the opportunity to kill Kakashi, he will not prosper because Naruto will save him. No more shall Naruto allow another one of his sensei to be killed by a former student. So the fight between the two erstwhile friends is inevitable.
Sasuke vs Naruto part 2? If Naruto and Sasuke meet and fight each other, then we shall see the MS vs Sage Tech, and then as a sort of climax, we shall see finally activating Itachi's gift to Naruto also. How exciting that would be! Especially for some of us who thinks this to be so soon.
Itachi's gift? Whatever that gift is, it is something that Sasuke would definitely identify as coming from Itachi. Then it would be Itachi vs. Sasuke. Finally and hopefully, Sasuke would understand fully who Itachi is and why he did the things he did. And then Sasuke wearied, battered (by all the successive battles he went through and then vs. another MS and Sagetech) and confused (because of Itachi's revelation) will come to the verge of another breakdown.
Madara interferes. At this point, it is most possible Madara would interfere again and whisk away Sasuke again from danger. In my opinion, there's no point at this stage in the manga that either Kakashi and Sasuke will die. They both hold important pieces in the myth of the sharingan. One is dark and the other the light side of the MS. They would fight to a draw and/or cancel each other out. But Kakashi is not only important for Konoha but also as the equalizer for two other MS wielders. He will prove to be the 'curse' of the Uchiha's hubris. Or the last of the active Sharingans that are not in Madara's collection.
Kakashi levels-up. In this fight, I hope Kakashi will get to see all of Sasuke's jutsus and suffer from them but survive so he'd be prepared in the future and develop further his MS because of this encounter. The last time we'd seen Kakashi battle against an MS (Itachi's), Kakashi was able to learn from it and then consequently develop his own MS. So we'd expect a Kakashi development here.
Karin in Konoha part2. Karin will play an important role in divulging the Moon-Eye plan of Akatsuki and the powers of Madara, Sasuke, and Zetsu. (And she will also have a 'thing' for Sai (albeit another passing fancy because of his semblance to Sasuke.hehe)
Not Sasuke? All three reputable chakra sensors who know Sasuke (Karin, Sakura, and Kakashi) concur that this is definitely a different Sasuke. I am now really positive that Madara did something to him (that jutsu Madara and black Zetsu did before taka attacked the kage's summit), it is to hasten and to exploit the darkness in his soul. that is what Madara was referring to when he said he'll 'speed-up' the moon-eye plan -- a plan that has sasuke as one of its major ingredient and requires that Sasuke reach the highest potential of his MS, and lose his eyesight so he would be forced to take his brother's eyes.
Moon-Eye Plan speed-up. Now this Madara-Zetsu jutsu most probably is similar to what Madara did to the [third] Mizukage. Definitely this jutsu was what Ao was referring to when he mentioned what happened to his previous Mizukage, and what the present Mizukage was suggesting when she stated the rumors that the [third] Mizukage was being controlled by the Akatsuki. Unfortunately, we won't be hearing anymore from Kisame the reason why he called Madara the Mizukage. However, we get the idea already.
