Hmm well from the very start Naruto was after only Sakura. Hinata didn't even exist for him during part one. Or she existed but she tried to approach him in her own innocent way and got quite frankly ignored.
But. People grow up, they mature and they value others differently in the process.
So it was about time Naruto stopped being childish and get over his childish crush on Sakura. Kishimoto did this (at least kind of). It started in the Pain arc, to be completed in the war arc. Naruto obviously noticed Hinata and is (hopefully) able to understand that she is the type of woman that he needs.
To conclude, my opinion is that it would be better for the story and also better as a way to pass a message to the manga's teenage audience if he ended up with Hinata. However, there is still the possibility that we won't have any pairings at all and Naruto might even end up a little dead
(p.s. I can't help but to underline the fact that Naruto had more feelings for Sasuke than any of the 2 girls mentioned though, and you have to agree on that)
