That would be better than what we got, but would still be lackluster in Naruto.
I don't think you should hope for another ending. When the chapters are leaked to the translators they are leaked as an whole comic. Naruto may be big but cant imagine WSJ ruin an entire issue for a prank/anti piracy bit.
I think the best way to interpret the twitter is to understand that 699 and 700 chapters aren't the the real ending of Naruto the series. Meaning more will come after it and clear things up. But Monday all of Japan will see those chapters.
Yeah, it's not just Naruto that's leaked, it's the whole WSJ Issue. I completely agree with the bolded part, too; I take it to mean that the Naruto series will continue, as we've already seen, as a series of short stories published in books. Guys, we're getting Naruto LNs... that are not about Naruto, go figure.
So this movie will just add more salt to our pain?
Face palm* Oh Kishi, do you hate NS shippers this much.
To top it all off Salada or whatever her name is, in spanish her name means Salt/salty 
I bet the movie will serve as both a retcon and an explanation of the asspull that were those final chapters.
And yes, Salada literally means salty in Spanish, which means that in Japanese, which would be Sarada I think, it would mean something else... or nothing at all, because Boruto? Really? Bolt?
The story pointed to NS as endgame, the last two chapters were a mess: characters OOC, ignoring years of development; nothing about the aftermath of the war is explained; several characters didn't even appear in the last two chapters, e.g., Yamato, important character in Part II/Shippuuden; Orochimaru, the goddamned main villain of Part I; Taka, Sasuke's team in Part II/Shippuuden; the epilogue was absolutely terrible.
