That could work, would be great.
It could work, and the fight would last for as long as it takes the Hokage to get involved and help seal Kaguya.
if that does happen I can't help but think it will be Sakura. There are a lot of parrallels between kakashi's team when he was a child and narutos team. Rin was killed "for a specific reason" and I have a feeling if it is Sakura either naruto or Sasuke will have to kill her. Maybe Sasuke will kill her and then naruto fights sasuke.
Good point. I could see Naruto turn on Sasuke to protect Sakura.
