For me it depends, while I would want to see a clear answer from the land of iron events, it really depends on if Naruto was forgive and forget with Sakura and he overlooked what she did cause he loves her that much, unless we get something like Naruto going, "I understand why you did it, etc, etc, I don't know what Sai said to you and he did tell me why, etc," maybe naruto mentions how while Sai may have been right in that Sakura and Sasuke did cause him pain, they also were more importantly his sources of strength.
No need to say how we want a forehead revelation to come up now with the 631 events.
I would actually think another major one would be Naruto discovering Sakura was aware of him loving her. That revelation Sai brought out did impact Sakura, but Naruto telling her why could be a big difference. 457 is still up in the air just waiting to make a comeback.
One thing I would like to see though is if the high moment came especially between Naruto and Sasuke, she takes Naruto especially now with hokage position open in the future.
