Bandai Namco has announced that Road to Boruto, an expansion for Naruto Shippuden : Ultimate Ninja Storm 4 will be released on Feb 3rd of next year. In this expansion you will be able to play through the story line of Boruto: Naruto the movie.
New characters available to play are Boruto Uzamaki and Sarada Uchiha, no other characters have been announced yet but I wouldn’t be surprised if you could play as other children of other ninjas.
The expansion will likely be $19.99 and will be released on PS4, Xbox One and Steam on PC. Look for it early next year.
