Personally, it seemed to me like there was plenty more story left to be told -- the ninja village, the assassin association, Momiji's company, Yoshida... Sadly, I don't think one more volume will be enough to tie up all those plot threads. And now it seems like a distinct possibility that the end of Chapter 49 is going to be as explicitly romantic as Satokonoha ever gets.
Idk. I don't want to sound too cynical. Let me put it this way: I'm confident the final volume will be a great read, but I'm not expecting it to give me everything I want.
