Speculations: Chuunin exams
Examining how the plot has been unfolding lately, it might not be a stupid to assume that there will be another in-depth Chuunin exam taking place.
Hear me out.
1) Saskue has now betrayed Orochimaru and whatever the outcome, it would most likely delay Orochimaru's attempts at stealing Saskue's body (if this will even happen is unlikely). News of this will probably reach Konoha which may relieve the urgency of having to find Saskue, allowing Naruto to participate in the Chuunin exam.
2) With the lost of 3 Akatsuki members now, this is a serious blow to the organization. They would most likely need to regroup and replace their fallen members before they decide to move again.
With the occurrence of these two events, it is not improbable that Kishimoto decides to do another Chuunin exam. This will serve to both, give Naruto a chance to become a Chuunin, but also to introduce new characters into the storyline.
Discuss.
