Well since this poll is a wee bit biased (It's posted on a NaruSaku board anyway... XD It's ok. I think this is a good thread to discuss other possibilities.), I will have to look at this not as a fan, but as a fact analyzer.
1) NaruSaku (eh heh let me elaborate) - Just using common sense, would the main character of a shounen manga ever end up with someone that he hasn't been interested in for a while? Even in DNAngel, when Daisuke switched his affections, he still liked Riku for a long time before they started dating. There are a lot of other common sense reasons, but that is the most prominant for me.
2) NaruHina AND SasuSaku - If Sakura and Sasuke ever got together, I have a feeling that Naruto would see that he had to move on and Hinata would probably help... if she could not faint for about two seconds. It wouldn't be a happy ending for him though. He would feel awful about seeing Hinata as not the one even though she cares for him. Sakura wouldn't be making much progress either... unless she truly had the patience of a Goddess. ( In the end, NaruSaku might happen anyway due to the realization that stuff's not working out.)
3) SasuSaku - Well Sakura has a lot of initiative. I think that she would make the first move and MAYBE start something... Hinata just doesn't seem like the type to get things going and Naruto's not actively seeking her out, so Naruto-kun might just end up pairing-less in this scenario. :shamefulcry0js:
I hope this all made sense!
