SPOILER (click to view)

The last image of the cap 401 leaves the impression, by the look of Sasuke, that he finally overcame the idea of revenge, of course, his goal was finally reached. But what now?
For the story told by Madara, Sasuke would not have reason to take revenge of Konoha, and yes, only mandar the advisers for an asylum and eliminate Danzou. What is clearly one of the intentions of Madara. The leader of Clâ Uchiha already livrou his clâ and now left the village of Konoha.
Now comes the theory: Sasuke, convinced by good meter of stories (not that the crop of Itachi is wrong, on the contrary), to enter the Akatsuki, and will continue to plan Itachi, which was still used to watching the organization of Konoha into.

But one thing is still confusing, and Madara Pein should be playing the cat and mouse within the organization, and by telling half truths. Pein, which calls itself God himself, not rebaixaria to be a subject, his personality in the fight against Jiraya makes that very clear. For it seems, the plan is to have him control the world of ninjas, controlling the whole arsenal of Bijuus. Madara he gave the order to capture the nine caldas, and he obeys because it is convenient.
Already by the side of the Uchiha Madara, he knew that Itachi was still a spy of the sheet, I believe Pain did not know details of that because it would give a bit of confusion and sobraria only in the Hidan Akatsuki, that pq was immortal.
Now, for what seems, Madara faithful will have a new partner within the Akatsuki, Sasuke. And now comes with moral vai ultimately killed three members of the organization, should wear three rings.
Then within the akatsuki, a division of whom vai stay with the big prize at the end, for while it is still missing because in order to capture bijuus.

Do not connect to offenses, only that I do not turn the topic at guerrinhas stupid.
The image of Sasuke looking to the sea, represents the thinking that he is doing td on the stories and events that he presencisou and he only exitem 2 ways:

-- Konoha get back and try to annihilate the evil of the town, restore the image of Itachi and erect a new Uchiha clan, without máculos the past.

-- Connect to Madara in their revenge, destroying the malignant Konoha and reerguer Uchiha clan of the past.

Unfortunately not get to know for sure what will be his decision and we can only wait for more information.
Frankly I naum know what happens with the vai Sasuke here looking forwards as if it were behind the Danzou and the whole corja he would be back looking for revenge ... I wanted very much that he returned to Konoha and it again on the side of Naruto (almost a utopia for now). If he comes to Akatsusk we can expect any turnaround in history who knows ... please note that it pasou Oro in the leg and had that in mind since it was to join him !
