I don't really care whether Katie is pregnant or not in the epilogue; perhaps it would be good if she and the MC discuss it first. I do hope we'll get a good wrap-up for the main cast, but I think the dystopian/cyberpunk setting makes that tricky. This is a world were soulless corporations are supposed to be ascendant; the little people can never be 'safe' from them in the long run.
I think the optimum outcome would be to see how our surviving heroes (all of them, ideally) have grown stronger from the experience and to get a clear sense of where their path will lead them next. But leave the results of those paths to our imaginations.
Chapter 10's development time was actually much less that Chapter 9:

Now, as you may recall Philly took December off while working on Chapter 8. If we remove those 31 days, the development time for all three chapters of the second act have been in the 130-140 day range. If that pattern holds Chapter 11 will be finished by January 15 or so. Chapter 14, the theoretical finale, would be released around the end of February 2023.
Odds are many things will change between now and then, but these are the numbers we have for now.
