Shock announcement.... shock announcement...
Personally, what I would like were if due to Naruto's loss kyuubi refuses to give him chakra any longer. Then Naruto had to learn new jutus (not just one normal [k.bunshin] and one finisher [rasengan]), behave like a ninja and get some tactical skills. Stopping the pranks/shouts and start becoming a real ninja who takes his buisness serious. Then we would see how good he really is plus it would get interesting again. A total restart from near scratch.

Trained by Kakashi (anti chidori lessons), Jiraiya (general training) and Gai (anti sharingan). As Kakashi said, Sasuke won't gain anything from the curse seal and around ep 330 they will meet again. After that kyuubi will acknowledge him for beating Sasuke and he will get chakra once again.
As a result we would have Naruto as, well, personally, I wanted him to be from day 1.

On the other hand, maybe he just gets some clothes that do not burn your eyes out of your skull.
