Well, my thoughts on the Big 3...
~Naruhina~
Yes, it's a cute idea, but it isn't realistic. Aside from the fact they were together for ages with no development, the whole "opposites attract" statement is misleading. Yes, seeing something not in yourself in another may generate a spark, but that's all. Sparks fade quickly, and if there is nothing in common, nothing to relate to...how can it be a relationship?
There's also the fact that Naruto barely knows of the poor girl's existence, save for the Chuunin exams portion and when they've directly talked.
~Sasusaku~
I like it, but in no way do I see it happening, especially if Sakura finds out about Sasuke's motives in the recent manga. While I believe Sakura felt more than a crush for Sasuke, there is no way you can convince me it is love, just because of the fact that it seemed selfish. Even at the goodbye scene, where Sakura told him meaningful words, it was all about him staying with
her, ridding himself of his loneliness with her.
And while I do think Sakura is Sasuke's favourite girl (well, actually, Karin might be getting there lol), his feelings for her are purely platonic. Or, if I'm wrong and at that time he left he did harbor romantic feelings for her, it doesn't really matter.
He chose revenge over love. It was his own mistake.
Add that to the ambiguity of Sakura's feelings for him during the Time-skip and her growing feelings for Naruto...
Yes, don't think it's happening. As cute as the 'girl healing with her love' thing is, that's shojou.
...Which Naruto isn't, but rather is a Shonen...
~Narusaku~
...And Narusaku is the typical shonen couple
I love this couple a lot, because I like the development and their individual characters.
What I first liked was Naruto's devotion to her, even though I didn't think they'd be a couple in part one.
Even when I liked Sasusaku more, I felt for Naruto. After the Gaara fight and hospital scene I genuinely thought he loved her, and seeing all his 'D':' faces when confronted with her feelings for Sasuke tugged at my heart strings.
However, after Sakura's revelations about Naruto, his promise and then the promise of a lifetime redux...
I thought I'd wait and see what happened after the time-skip...
And you all know about that, so I'll save commentary for another thread
So, due to development in the manga, I think Narusaku is most likely.
And that's that
