Its only natural that Naruto is gonna get who he wanted from the very start, in other words: Sakura. So sorry, NH fans.
Ah, what the hell... I'll bite.
See if you can reel me in.
How is it 'natural' for Naruto to get the girl that he started the series wanting... and has since turned down?
As much as anything - that illustrated Naruto's growth in character. If you remember, at the start of the series, he was willing to disguise himself as Sasuke in order to spend time with Sakura. A stark contrast to what we see, there - where he calls her bluff.
Not to mention that what he has wanted all along is now present in Hinata.
Sakura may have been the 'picture' he started the series wanting... but the life, relationship, and respect he's been looking for pretty much radiate from Hinata. It's also quite possible that his taste in women has matured a little, as well - and the novelty of pink hair is not the focus of Naruto's interests any longer.
I mean - let's look at current events. Naruto pretty much sends Sakura packing and then he turns around and takes Hinata's hand after the two essentially tried the same thing - Each was trying to get Naruto to stop shouldering all of the burden by himself. Of course - the fact that Sakura has no tact while Hinata does made a bit of difference, there - but it's quite obvious that Naruto has no objection to this person being a part of his life (Hinata).
Though it would be absolutely hilarious for it to turn out to be NaruKarin. Judging from Sasuke's reaction to her, he might just try to brush Karin off on Naruto (or anyone). It'd be quite priceless.
