Of course not. As a fan, I want it to last forever.
It wont end after the war ._. there will be another arc after .
I DO want Naruto VS Sasuke. Whether it's violent or friendly, to the death or as rivals- I want it. I'd be disappointed with anything less.
I also want the series to end with a small epilogue (VERY SHORT) where Sasuke says goodbye to Itachi, Kabuto's orphanage friend finds him in the cave and he wakes up and a funeral for the dead among other things. If Orochimaru takes control of the battlefield like I want him too, then- I want one more arc.
The ending is pretty obvious, Naruto vs. Sasuke in chunin exam final round.
