im def not one to say that there isnt a possibility he wont end up with Hinata, Kishi puts things and has character's say certain things for a reason. However, from what i have seen in the manga, Naruto and Hinata's interaction top out at about 3 for the entire series...im sure he's definitely acknowledged Hinata as a person by now and what she has done for him but if Hinata wants to get someone like Naruto's attention, shes going to have to replace Sakura basically and actually help Naruto accomplish his goals aka Sasuke and hokage to really prove herself to him. It would be weird for Naruto to have liked Sakura soo much all this time and then just bam 180 turnaround. If you look back at the confession, there are several theories you can make but regardless on whether Naruto thought there was simply something she wasnt telling him or whether or not she really wasnt telling the truth, he was reacted like someone who just got told they won the lottery..in total disbelief and immediately assumed it false because that is one of his goals! Getting with Sakura. The only way Hinata and Naruto end up together is if, well, Kishi does decide a 180 outta nowhere or if Sakura turns Naruto down because she thinks she doesnt deserve him. He def wont trash Hinata either, hes not that kind of character but that confession of hers doesnt canon NaruHina in any way, not til we see Naruto actually react to it more than saving Hinata back.
