It's fake because what you reported as from an interview wasn't from an interview but from a tiny blurry unreadable photograph of some text Kishimoto wrote that some fan claimed it said that. the real Takl repeated this in the thread you got the info on Nf he'd already stated this yesterday in the movie thread. Takl doesn't have the magazine, he was reporting some rumors on 2 chan that he had read. The opening poster on the thread you took it from trolled Nf by just reporting the rumor from someone who claimed to have the article and claimed they saw Obito in the the text.
So yeah, claiming this was said in the interview is completely false. And I say this as a person who was in the Madara's soul was put into Obito's nearly dead body by Orochimaru camp. I still don't rule that theory out.
