So yeah, I've finally understood that Sakura is falling in love with Naruto, and he's been in love with her all this time--it's beautiful. It's a little hard to explain, but I'll give it a go.
What really did it for me was the realization that Sasuke and Sakura's bond has never been romantic. It's Naruto's and Sakura's that's always been romantic.
Just the other day I stumbled across some clear scans of the scene in the Forest of Death where Sakura hugs Sasuke--and an accompanying translation. The translator pointed out that just as Sasuke is retreating from the curse seal, in very small text, he says, "Kaa-san?" And Sakura says, "Hai."
He's calling out for his mother, not a girlfriend. And Sakura understands that. In fact, I'd even go so far as to say that when Sasuke and Sakura reunite, Kishimoto may reveal that Uchiha Mikoto's soul is linked with Sakura's somehow.
I really have no idea what's wrong with the people who ship SasuSaku. That's just disgusting. Sasuke has never wanted anything from Sakura but someone to mother him--and Sakura has understood that since the Forest of Death. Naruto, on the other hand, has always loved Sakura truly and passionately. Sakura just wasn't mature enough to accept his love at first. Now, she can finally join with him in holy love.
I figure the series will end with Naruto and Sakura getting married, maybe at the same time as Naruto becomes Hokage, while Sasuke moves away from them and marries some random girl to continue his clan--maybe Tenten or a girl he meets in Sound.
