Hmm... actually, considering this is shounen (not shoujo) I think there won't be any more pairings in Naruto. I would love to see many couples together and I definitely want to know how the NarutoxSakuraxSasuke triangle ends, but I have to insist: this is shounen.

Aw, whatever...
Let's see...
Naruto. I don't think so. It's true he's been closer to Sakura but my impression is they're more like siblings. I just can't see them as a couple. They're more like a brother and a sister to me. Also, I like NaruHina better than NaruSaku.
Sasuke. I don't know yet. Sasuke's got a lot of issues. He has to get over all of those traumas from his past and everything he's going through right now. So if SasuSaku
ever happens it would be in a REALLY distant future. But I think it would be a great chance for Sakura to get close to him and prove him she's not just a crazy fan-girl if she's there to truly support him and help him get through that hell. Though I don't know
how that would happen...
Lee. Not gonna happen. Sorry for him, he's a nice guy but I think Sakura only see him as a friend.
Sai. Not even an option. <_<;
