Like Sasuke and Naruto battle after Madara and Obito are taken down ? If that so, Naruto has to be in a good condition again, and I think there have to be a break, few chapters in the village or something, before that battle.
What you said is that Sasuke can go back like in part 1 in attitude towards them if Naruto talks to him to patches things up. It's rushed for Sasuke to be like that as in now. Don't you think that this is more probable at the end after everything is over ? If Sasuke will still be alive, hopefully for this option.
The thing is Naruto is hurt, torn, and less powerful than before. While yes he can get one more powerup judging by this chapter, maybe, that would only mean Sasuke is behind him a lot. He was annoyed when he felt Naruto's chakra from far away. I once thought that the theory of mental problem will play a role but this time, it's about Naruto instead of Itachi. I don't know why but I think Madara was effected by Hashirama more than anything or at least put his madness on him. I mean Hashirama always get the good side while Madara kept getting worse in terms of loss (brothers, respects, etc). But we'll see.
The point is that there's a chance of break or a small arc, much like finish the fight arc like some anime/manga have, even after settling a huge war. That said if Naruto keeps getting powerup, don't you think Sasuke should well power up too? I do, especially in the condition that Naruto is in. That's pretty bad when you can feel your rival's presence without being a sensor.
Oh yeah, of course. The end is the right timing.
Depends on what type of attitude you're implying he's the same as vegita he's still arrogant, just look at how he apologized to Karin.
To be fair, T XD is right about the attitude part with Team Taka. He's not as arrogant, but he acts like a leader since these guys are crazy in their own rights. When you look back at Search for Itachi Arc, you pretty much got to see a glimpse of the daily life with them in that one chapter when they rest. It's funny and lively. Sasuke stop being himself truly in Kage Summit Arc because dark chakra was overcoming him.
Anyway, back to the point, Sasuke can still be what he was when it all ends. That doesn't mean he will be an a**hole still to Sakura, but he will still be like "Back away..." in a normal tone, much like to other girls. I mean Sasuke still got that impression of "Um..." with Karin when she rubbed him, let alone in public. It's not like we're seeing AU! Sasuke. I guess the last (latest) impression is what people always going to assume that will be it for now on. I say wait. For fun, well how else Vegeta managed to get married? Funny, if you go by anime, SK is actually similar to VB, minus obsession, but I digress. To each of their own.
