I hope there is another time skip to show more growth in the characters of Naruto.I have had the idea that there is gonna be another big Ninja war. If Naruto had more time to train with the 1000 x clone trick he could develop alot more.
Also I am kind of intrested to see how konohamaru will develop as a ninja hes kind of been ignored. I Think when he grows up hes gonna be bad ass.I wish we could see his team go thru the chunnin exams maybe at the end of shippuden.
There are still alot of plots in darkness like Kabuto and Root that we have not seen deleop yet. Maybe Kabuto will develop a way to neutralize the Sharingan.
And if Itachi dies 1 way or another will Sauske form his own ninja village to rebuild his clan.
Post your ideas..
