It'll end up with Sakura and Naruto.
I see that the three of them, Sakura, Naruto and Sasuke will succeed where the Sannins didn't.
Naruto will marry Sakura (Jiraiya + Tsunade).
Naruto will save his best friend, Sasuke (Jiraiya + Orochimaru)
And a few other things that I don't feel like writing down.
