Seems like my analysis theory is turning out to be correct so far:
Chapter 1 ends at the 20 minute mark
Chapter 2 ends at the 32 minute mark
Chapter 3 ends at the 43 minute mark
So go by this pacing alone we've got roughly 3 to 4 months left before the Boruto Movie content ends, and I guarantee you this is how the next 3-4 chapters are gonna end
Chapter 4: End with Naruto finding out Boruto cheated by using the ninja tool after his fight with Shikadai
Chapter 5: Ends with Naruto saves Boruto and is supposedly dead!!
Chapter 6: Ends with Sasuke and the 5 Kage take Boruto to save Naruto.
Chapter 7: Ends with Momoshiki gets defeated by Naruto, Sasuke, and Boruto.
SO either at the end of Chapter 7 or starting Chapter 8 we'll be getting all the new content and that won't be till either This Upcoming December, or January.
