LOL I think there is going to be more about Sakura. I can't remember them ever mentioning her father. You know her mom because she talked to her through her room. But I dont ever remember her dad being around. They are always talking about how she is able to control her chakra better than most people including Sasuke and Naruto. But maybe she never had anyone there to teacher he cool jutsu because her parents are just civilians. She only knows what the school taught her.

And the whole her having two minds is just cool so I hope they do something more with that. I wonder if they will ever mention more about her dad. From what I notice its mainly just the dads that are the ninjas.
