Well, Paulbee, who Naruto chooses has direct bearing on this manga because way back when, Kishi decided that Naruto's way of the Ninja would be not to back on his words. With that in mind, he has confessed his love for Sakura and has not changed his stance since he first did. So what does this mean? If he suddenly decides that he doesn't want to be with Sakura anymore, it means he's gone back on his words, his ninja way, and this breaks down one of the foundations Kishi set for this manga, making it totally hypocritical. Kishi doesn't want this to happen obviously. So it undoubtedly has to be Naruto x Sakura at the very end, lest Kishi make Naruto a hypocritical jerk.
Now then, I've looked at this dispassionately and have still arrived at only the possible outcome of the love interest. Sasuke is immune to bitches, that's why he doesn't react to anyone. With that being said, he'll end up with Hinata... BWAHAHAHA!!!
