Ahhh well Naruto and Sakura are not inverse, their from their reality trapped in the tsyomoni thing.LOL isnt that movie in an alternate universe where everything is inverse ? Going by that logic, Sakura is never going to end up with Naruto in this universe (manga).
Personally, I think naruto is going to die after defeating / controlling / suppressing Jyuubi.
The main point Narusaku fans use this movie, is because Kishi wrote Road to Ninja personally.
And did he focus on Hinata and Naruto, or Sakura and Sasuke? No, he didn't.
He focuses more on the Narusaku relationship, which shows that he probably favors it more.
I think Kishi knows what he's built in Naruto and Sakura, he's built a deep relationship that goes beyond, your simple childhood crush.
Also I doubt Kishi kills Naruto off before he becomes Hokage.
