I don't think it will end anytime soon. There are way too many storylines to wrap up and lots of people to kill. Hmm let me try to count them up;
1. Ok we got all the Sasuke questions
2.We gotta find out what's the deal with kabuto and than he needs to die
3.We need to uncover a crap load of stuff about Akatsuki (wgo is the leader,what is their goal,who are all the members and than they all have to die in some huge fight.
4. We need to know about Tobi and if he turns out to be Obito I will kill myself.
5.We still gotta see a crap-load of training and advancement from Naruto.
Hmm, that's all I can think of but I would say we have atleast a year of chapters.
A genius can be defeated through hardwork.....
