I think we wil never know how naruto's parents are. i think everybody wil agree that naruto is very simular to the young goku, in the dragonbal manga. a loud, strong, litle raskel. but there minds where also the same. goku never asked in the manga how his parents where, or where he came from. he just looked ahead, and did't much thinking of the past. naruto is imo the same. i think he doest care about his parents he just wanted people to recongize him (begin manga). i think it won't cross hsi mind ho his real parents are. naruto (this is different from goku) is an emotion type of person. every thing he does goes through emotions. (example: if he needs to learn something, first he must feel: do i want this, wil it be fun etc. Then he can go further with his learning style,) this even effects his way of the ninja. so difference between the 2 of them: naruto is wonderingh how it would be if iruka would be his father. Goku on the other hand had gohan as his grandpa. i think because of the link, or it is the link to dragonbal manga. naruto wont ask about his parents, or mabey kishi wil to please the fans show how naruto's parent are.
