my guess is that either A) sasuke fights naruto and gets his ass rocked, then someone like Kabuto steps in and drops Naruto causin him to fail bla bla bla B) sasuke beats naruto (of which i dont want to happen, but seein the situation it is quite likely) C) before naruto even *sees* sasuke someone like Kabuto rocks him ending that problem, but the end result is i dont thik that Naruto can bring back sasuke for storyline purposes, and it really would make a lot just quite a waste as how can A) sasuke advance even if they get him back? do you even think they would immediately do anythign with him even if he is the sharingan successor? he just went traitor to the leaves-----if i were them even if they brought him back (apology and all) his ass would rot in a jail cell until he had a beard. and no itachi isnt ultimate---yes hes pretty freakin damn strong and stronger than basically anyone we have seen as of now (save for perhaps jiraiya, and others of that sort that are a good coutner for sharingan, or the Hyuuga head) and sasuke is quite behind in catchin up to his brother. when itachi was sasuke's age he was basically the head of ANBU teams---sasuke is still not only a genin, but might be at best chuunin level in the moves category---from what ive seen i think ANBU is probably LOWEST upper chuunin level, to the jounin ranks (most likely all of them id think), so just think bout that. Sasuke would NEED something like a boost from a curse seal or some shit to catch up cuz hes nowhere near close and at this rate i think itachi will still be leagues above him. ill stop my rambling tangent with this---- sasuke most likely aint comin back and the series will probably time jump (everythign is basically set for this save for sasuke leaving to grow---i mean really even Lee's problem has been solved, Gaara is a friend of leafs, and Shika/Temari thing is goin as i guessed a while ago also) most pressin problems have been already solved and there isnt much left goin for this tangent---it might jump to where the genins are now chuunins, perhaps one or two being jounin. but most things have realy come to a close and there isnt much left to do unless kishimoto pulls somethin else out of his ass, but doubtful that he will
