That would make sense. Although the statement doesn't get rid of all rival pairings (SS is from the main triangle, too), it wouldn't make sense for Kishi to say something to rule out other pairings before anything's revealed in the manga.
Yeah, that's way too much info to be revealed in an interview. Kishi's always really vague, especially when it comes to stuff like that.
Look what i found on NH forums: Quote: SJ: There are several cases of unrequited love in Naruto. I mean, Naruto, Sakura, Ino, Hinata and Rock Lee are all in that situation. Will any of them ever have their love returned?
KM: Ah. Well, perhaps. You're right, there are lots of cases. I'd never really thought about it until now, but they do make you sympathize more with the characters. Maybe at least one case will be requited. I would just have to figure out how to go about it.
SJ: We're hoping Hinata gets her chance.
KM: Me, too.
Yeah, I was about to mention that this is the closest real thing to that supposed interview.
Whether it's fake or not doesn't matter. I don't think you need an interview to confirm that NS is the only pairing that becomes canon. I mean, it's the only pairing that actually matters, especially given all the development put into it.
Very true.
