I would like to see another Chuunin Arc. But, obviously something with a twist or more flavor than the last. New battle grounds and new styles to the battles.

Will Naruto take it if there is one? Probably not. I would not mind if he doesn't. I think it's somewhat moot. We know his skill exceeds that of Genin. I think Jounin would be too much, as Neji is the only Genin we were introduced to that has achieved said rank .. which explains why Neji's deserving of more page time! Alongside Lee, of course.
