You're overthinking. Stay calm, and wait for the last chapter. For me personally, NS is canon.
all evidence would agree with you. I still think its very possible but if he starts making sakura into a character that supports Naruto as a way of rewarding him for loving her, then it makes it seem like she's thought about his love, and although doesn't reciprocate, wants to support him.
NS has the best chance but unless Kishi is holding it out till the very end, and the itachi sakura image evil posted did just refer to a forehead moment, I don't see naruto confessing, I don't see sakura finally opening her eyes. It's gotta happen in 699 or at least hint at it in 699. she's gotta show signs of confliction and positive romantic feelings towards naruto otherwise kishi pushed it into the gray area and we'll have to rely on a movie to fill in the gaps, which would make no sense. I sincerely doubt he's going to show no sign of sakura returning naruto's feelings and then jump 6 years in 700 and show them married with kids. He's going to have to hint at it in the very least in 699
