Theory: Chapter 4 might end of the storyline

The reason I'm thinking this is because not only is ch4's theme just ch1's but backwards, but during the fracture event, there were flashbacks you can interact with showing chapter 1's live events, from the season 4 rocket launch, to the season 9 fight, so what I'm thinking is something similar may happen to the Ch 4 island. The reason why there haven't been any live events? Is probably because they're waiting until season 4, just like in chapter 1. What will happen is beyond me, but whatever does will ofc put the zero point in danger once more, and kill the map. But what will happen after that? Will we get a new map? Will the story restart and we get out on a updated version of chapter 1? Will maybe the 1, 2, 3 and 4 map all combine to make the Chapter 5 map? Will it literally be every map smashed together or will it have it's own look but with almost every past location? What do you guys think?
