To be clear, there are at least three updates left: The first will be a mid-cycle update that includes consolidation of the two divergent codebases and a massive cleanup of the earlier chapters and the removal unused images, sounds, etc.
The second will be the epilogue which looks ahead at how your ending pans out. Effectively the final chapter.
The last will be our revamp of the first 2.5 chapters to bring things up to our state of the art. Call it the "remaster."
We are threatened with one first update that will remove images and sounds and whanot - cleanup of earlier chapters.
What could they possibly need to ret con or effectively delete from the story, if they actually wanted to wrap up the story threads that we would save in our end of chapter 9 save?
If they go into all the other chapters to cut and change and move stuff around ... it clearly sounds as a de facto rework:
are we sure they will ever come out of such a huge endeavor by the end of this year?
Plus - that is the first update - the second update in the time frme starting today until the end of the year - is supposed to be the epilogue promissed.
