It seems like a good prediction but there are so many flaws in this.
1. This much detail in one chapter would not happen and would be cut up into multiple chapters.
2. It seems like Naruto and Sasuke need to have a chapter where they can put aside their differences to work together.
3. Even though we have read chapters about Naruto interacting with his parents it seems like minato doesn't remember those interactions so maybe a catch-up chapter between father and son.
4. Maybe on the way to the battlefield they (the big four and company) run into the five kages, help them out and bring them along.
What I've come to expect is that with the end of this series coming so close, we need to cover all the possibilities of what could happen and make the final battle the very best. Also similar to the fillers in the anime shows, it somewhat happens in the manga but these cut-offs have more relevance to the main storyline.
Plus we cannot expect to jump right into the final battle until the storyline becomes a little bit more dramatic (like Naruto is about to be defeated when Sasuke appears to save him) in my opinion.
