After Naruto's years off in training, we know that Hinata's still in like with Naruto, so I'm still going
to push for that. I cannot make too many judgements on who's going to end up with Sakura.
Perhaps Naruto doesn't care about this love stuff anymore, as, if we link the filler arcs (Admittedly, I
didn't see all of them) with the manga, he focused his entire being on "rescuing" Sasuke.
Perhaps Sakura will fall for Sasuke, as she has worked so hard to get him back.
Perhaps Rock Lee and Sakura's relationship is strictly professional. (Though I'm pushing for this one as
well)
Perhaps Sai could get in on all this when he learns to socialize!
