Kishimoto-sensei said in an interview that there will be a new character introduced sometime soon. I have a theory on this character.

After Naruto owns Pain, he'll help search through the rubble for survivors. He'll find a little girl who will look at him and ask "Where's my mommy?" Naruto will wrap her up in his jaket-cape thing and say "Don't worry, I'll find her." But when he does, he finds out the girl's parents are both dead. After he tells her about it (with care), he promises to take care of her.

What do you think of my theory? Do you have any other theories?
