Rivalry. Sakura -> Ino <=> Naruto -> Sasuke
Well, as I was re-reading the manga for certain purposes, I got to this fight, from back of Part 1, between Sakura and Ino. And I remembered that their rivalry/friendship is just like Naruto's with Sasuke, as stated by Kakashi himself.
Let's go a bit in time. As we know, Sakura and Ino rivalry arisen back in the days, for Sasuke's acknowledgement, as Ino herself remembers back in the Forest of Death situation.
Well, similar, Naruto's rivalry with Sasuke was for popularity.
Later on, in both Sakura and Ino's case as in Naruto and Sasuke's case, the rivalry turned into something more. Both Sakura wanted acknowledgement from Ino, as well as Naruto from Sasuke.
If we go again back, with Sakura's and Ino's case...
What does Sakura say? I wanted to be like you, you were my goal.
Now, let's look at Naruto's case with Sasuke.
What does he say? I always wanted to be like you, I aspired to be like you.
Both Sakura and Naruto have looked for acknowledgement from their rivals and both their rivals didn't offered that to them in the beginning.
Sakura's case with Ino.
Naruto's case with Sasuke
In the end, as we know, Sakura's battle with Ino, was a draw/tie and Ino finally acknowledged Sakura.
What's interesting, is that, at the end of the battle, they were portrayed as their younger selves.
And according to Kakashi, it all had to do with Sakura's inability to accept defeat and her inner desire to defeat her rival, Ino, which is as same as Naruto's with Sasuke situation, as Kakashi says.
Now, based on all these similarities between the two rivalries and this panel
My theory is that Naruto's and Sasuke's clash will be similar with Sakura's and Ino's clash given that at the end of their battle, both were portrayed as their younger selves and that, in the end, Sasuke will acknowledge Naruto as a rival same way Ino did with Sakura and in the end, the battle's result will be a tie, they will be friends, however, their teasing will always be the same, just as Sakura's friendship with Ino's.
Meaning, they'll acknowledge themselves, their fight will be ended in a draw, they will be friends, however, each own with his path. To be honest, I don't see Sasuke returning to Konoha,especially after he did. Not that he wouldn't be redeemed, necessarily, as I am sure the circle of hatred will be ended, however, I see him wondering around the world with Taka. He has already made his own way, his own team, his own lifestyle.
He'll just remember, acknowledge and never forget the bonds he has.
So yeah, this was basically my theory for those who asked me to post it here on NB.
