Thing to note was the wedding photo was intentionally cut off....and also some people are doubting the red herring due to Kishi's inconsistencies (from what I see right now, they could be intentional).
For instance, Sasuke having taken a Team Taka photo but no Team 7 photo.....please. Now I know Kishi did this so Sarada could find a picture of Karin but still its inconsistent.
Also, Sakura fainting. I feel like Kishi did this so he would no longer have to continue the conversation between Sakura and Sarada, build tension and all that.
Yeah definitely a callback. Ultimately, I think he did a good job. People are once again hooked and lets be honest, people would not be if it was about Boruto playing hide and seek with Naruto.
Boruto thinks he has it hard.....he has no idea. Sarada has already become my favourite character in the new series closely followed by Chocho. Chocho is awesome lol
