Spot on.
I think regarding this New Era Project that it could be one of three things.
- a continuation of the manga either with older naruto or his kid.
- a continuation of the anime which means a bunch of filler (like GT)
- A sequence of movies similar to whats happening with the DBZ movies
All of it has possibilities. I think the continuation truly depend on what is the ending or epilogue show. If we see naruto become hokage and his family, I doubt that no. 1 will happen.
The same thing about naruto son sequel with out change the title of manga.
So I think 2 or 3 is more likely to happen.
