i know in one of the manga covers it shows naruto as a juunin. but i agree with the time jump just because it is showing him as a kid right now. other series other then dbz has made time jumps. like initial D, ai yori aoshi, vandread (well it is split into stage 1 and stage 2) rockman.exe. i could go back to some older series from the 80's that has second series continuing from the 1st but those show be good examples. i wouldnt be surpised if they did make a new naruto series that it will have a sub title or and extenion to the title not no Z like the dbz fans are saying.
