well i thought about it for a while and decided that they are going to HAVE to illustrate naruto reaching his lifetime goal in one way or another. i also like the answer from animemaster about naruto heading down the same path as db/z. i don't know if anybody remembers this show but it was called Reboot. it used to be on Cartoon Network a LONG time ago. It was CG animated and in the later part of the series they characters enter a time warp or sumthin (i kinda forgot) and the characters were in another dimension all grown up. i'm jus using this as an example as some characters in a series can grow up and the series can still rock.
