I loved the confession part. Regardless of whatever truth it holds for the future of either pairing it displayed a lot of empathy from Naruto, cause it's obvious he could sense a degree falsehood in it. I haven't cared much for the future of either of the potential couples, but this might even be the end of Sakura + Naruto (She probably loves him, though not completely in a romantic context).
She doesn't want him to get hurt anymore, and thus figured this'd be the only way she could let off her guilt or at least try and put an end to him continuously hurting himself.
This is just what it looks like to me as of now, there might very well be a more complex reason behind it. I'm good with either couple, as long as there's proper reasoning behind it (Since that's what makes the story).
It's a real hard one to explain isn't it? I mean, it certainly wasn't her being completely true, but I think she was at least showing elements of truth.
Almost as if she knew what she was saying was right, but her heart still hasn't let go of Sasuke, but in her mind she knows she shouldn't.
I love how well Naruto understands the people he's grown up with though. It takes a lot of strength, I think, to turn down something you've wanted for so long, even if it's fake, in pursuit of the real thing happening eventually.
I'm not convinced this is the end of Naruto & Sakura yet, since she does know what Sasuke's become isn't who she fell in love with. I have to respect her admitting that. But I think until she really sees him with her own eyes, she might not stop having feelings for him. And at the same time, I don't think Naruto's going to stop having feelings for her overnight and switch to Hinata, either.
Love's never simple, is it? ;P
