Theoretically if The Naruto Gaiden series serialization was broke into three parts
Use this as reference
The way it can be broken down is 3 chapters for 3 stories and 1 for the final story.
The first part of the serialization would be Sarada's side story(3 chapters)
The second part of the serialization would be Boruto's side story(3 chapters)
And the third part being Naruto and Sasuke as adults and their fight as equals(3 chapters)
And it leaves us with one more chapter that can possibly be a prologue about
The hidden Akatsuki member and onion Uchiha, which will pave the way for the movie that will be about Boruto, Sarada, and Mitsuki.(1 chapter)
Total of 10 chapters.
About the third part, Kishi may not elaborate or illustrate their fight(due to the minimum chapters) and leave us with our own imagination on how it went down. But with a certain twist. Just as rivals held bets before them in a friendly match like Kakashi and Gai, Naruto and Sasuke wage a friendly bet as well--The loser of the spare must train the winner's child.
The final page would be right before their spare with Naruto and Sasuke doing the unison sign as adults before they spare
*keep in mind this is a theory and should only be looked as that
