According to ANN, it's part of that larger project (new era) that celebrates the anniversary.
It's not the start of a "new era". Although, it's not impossible it would set the bases of a "new era" for the manga if we have a timeskip and not an epilogue at the end of this arc.
The project's title (新時代開幕) literally translates as "raising the curtain on a new era," though apart from this movie which appears to be set at some point in the future, there's currently no indication of what this "new era" of Naruto media will entail or what it means for the future of the franchise.
The new era reaaly does sound like it will be the ending of Naruto...
I think it will serve as epilogue.
I've updated the OP with a complete translation of the announcement article.
So with Kishi being heavily involved in this project, could this be possibly be considered canon?
I say this because Toriyama is continuing his DBZ story through movies , so is Kishi going the same route?
I suppose that you could say so, I expect him to take the same route. Though I'd want Naruto & Sasuke to keep their recent powers in the movies, maybe they will fight in the upcoming movies or some new foes coming from outer space and maybe this foes have a connection as to why Kaguya was willing to build herself an army of WZ, it may also lead to Madara's comeback as well.
I think its too early to say if it could be canon or not, what if the movie is just a dream sequence or result of some time space genjutsu?
Well, given that this is just 1 part of a larger project, which just happens to be named Start of a New Era, I think it's safe to assume it will serve as some sort of epilogue or continuation to the series after the defeat of Kaguya.
An epilogue eh? Could be interesting... So what age do you assume Naruto is in that pic? When Obito was fighting Naruto & co, he mentioned that the next day is the anniversary of Kushina's death/Naruto's birth. So was Naruto turning 17 at that particular instance or 18?
Someone said something about Naruto keeping his current powers. I'd say he absolutely should if this is an epilogue...Don't want the shifting around of powers Naruto might use that is completely unfamiliar to us, rather I'd like to see him develop his recent arsenal of abilities (A buttload of kekkei genkai).
He is seventeen. The next day is his birthday, so he will probably turn 18 in the series.
The new Naruto look, looks just like obito xD
Official websites are now up. The movie's tagline on the official poster is "Naruto, the Last Episode." There's also a section on the official site that states "the fate of everything will finally be decided."
They also include higher resolution images of Kishimoto's sketches:
At 170 cm (or 173 cm?), he'd be about a half a head taller than he was in Shippuden.
