I won't be surprised if Kiba ends up with Hinata in the end... 
TBH I would prefer in the end to see Hinata without a boyfriend. I still see a little girl obsess to gain Naruto's affection and approuval and not a a young woman that can stand up on her own without constantly depending on Naruto positive attitude and nindo.
I think the best ending for her would be a closure regarding Naruto before anything else because I don't think she truly realize that Naruto loves Sakura ( at first seeing Hinata's smiling face in chapter 450 when Sakura hug Naruto was a hint that maybe she did know but the more that I think about it the less I think she does), she really need a reality check about his feelings and not just hers because that's all we see, her feelings but we never see her acknowledging HIS feelings.
