there is so many things he could do it is to much work to list them out
that's exactly true, but for every choice there is a reason, and a thought that went into in (especially with tobi)
I doubt that he just tosses a coin or spins a pencil to make a decision..
So i hope we get to see his reasons behind those choices were/are
and kishi better hurry, a in a recent interview he stated that naruto will end in about a year and a half, but probobly a bit longer, so that like 70-90 chapters, not that much if you come to think of it.
On a different note he said kakashi was going to play a big role, and was going to surprise us by being stronger
and hate it that in the same interview kishi stated that the end of naruto is decided, but the road to there is not, SO no matter what happens the end is set in stone.
