Here's part of a interview that was conducted 2006 in response to SJ asking how he will end it.
Masashi Kishimoto: Yes, I have the last episode
clearly drawn in my mind. I've already decided on
the layout, text, and scenes. Not just the story
ideas, but the visual ideas are solid.
All I have to do is just head toward the ending I
have, but there are still so many things that need
to be resolved before reaching that point.
Maybe I have thrown in too many ideas, so I need to wrap them up neatly.
He planned this fight head to toe since 2006, he has been developing everything to this point.
This battle will be 100% pure planned out, no asspulled improves..
