Exactly, Tricksie, and the anime even added Sakura having a cutely embarrassed smile when Minato said "Please take care of my son." to her. I mean, even this filler arc the anime has now is just damage control since SP messed up big, and even Kishimoto-sensei is doing damage control. How sad.
I dont watch the Filler hell I havent watched the anime since the pain arc. What is all going on?
I never knew it was confirmed, never really followed interviews and such. I guess what really made it have that little bit of doubt is there are numerous folks who translated naruto, so there could have been different interpretations for it. But you're right its w.e now.
