I'm really not sure what the plan is for Naruto after the New Era Project concludes. I mean, if we can say anything about what has happened so far, it's that there is a large amount of negativity directed towards the series throughout a lot of the fandom. Should the New Era Project fail, then what? What's next for them? Do they go back in time and continue to milk off of Part 2 through releasing more movies? Additional anime arcs like "untold stories from Naruto's youth"? Do they attempt to pander to the groups that they shunned through alternate realities and continuities? What about the games? From what I've seen, the games follow the manga's story, so what now that it's concluded? Just tell it over and over again?
Dragon Ball and DBZ did it with some of the movies not being in canon. Maybe SP and Kishimoto-sensei could retcon the retcons and fix their mistakes somehow. But a lot of die-hard fans dissatisfied by the ending will NOT check out the New Era Project EASY. I know I'm one of 'em
