I think if they had to pair everyone up it would go something like this-
Naruto-Hinata. Hinata likes Naruto and Naruto doesn't take Sakura too seriously. The only episode that makes me feel like naruto will be with Sakura is the one where she is healing Naruto after he transformed into the Kyuubi. Yamato says that Sakura really... Unfortunately they get cut off.
Sasuke-Karin. Kinda random since every girl loves Sasuke it seems. If Ino got him, Sakura would have killed her. If Sakura got him, Lee would've tried to kill Sasuke.
Sakura-Lee. Lee likes Sakura and vows to protect her to the death. Sakura could probably find something in him that she likes.
Temari-Shikamaru. They got the hots for each other
Ino-Choji. Umm... There's someone for everyone?
Neji-Tenten. Well they are in the same group
Gaara and Kankurou can go find some random Sand chick.
It would be funny if Kakashi started dating Kurenai lol.
