I don't think there's anything else. He was quite unambiguous that "the next chapter" (after Ch. 9) will have the big scene with Amelie that the players have been waiting for. That's the reason he decided to split Chapter 10 into two parts as "there are certain things that need to happen before Amelie's main event" (paraphrasing).
What's interesting is Chapter 10 was initially planned to be big with around 1000 renders. And then he decide to split it into 500 renders each. And then we got a Chapter 10 (first part) which was 1000ish renders in itself. Now we'll be getting Chapter 11 which is supposed to go beyond 1000. So, we're getting more than double content of the planned goal.
What's even more interesting is that in a pre-Chapter 10 report, he mentioned it takes him "4 months to finish 400 renders and 6 animations". And the latest Chapter 11 progress report has him at "600 renders and 5 animations" after 4 months.
And this 600 renders+5 anims have been done while he's swamped with his full-time job. I'm super impressed, to say the least. And to know that the holidays will see him moving forward even faster is just beyond amazing.
