If could very well be, Kishi's had a few different roles in this movie. He was the character designer, one of the original story writers of it, and also the supervisor of the story as well. We'll have to wait and see but it's supposed to be connected to the original story and possibly after the events in the manga. Since Naruto is a bit older, there could be a time skip that this movie will represent but only time will tell.
Nice new threads on naruto! He's looks cooler than I would've imagined after a time skip. Glad they didn't make him look like minato...even tho minato is awesomely drawn
