Considering Orb's usual schedule for the AML previous updates, aside from the possibility of a pleasant Christmas surprise in the form of an unexpected update for that special day on the calendar, Orb typically takes around a month from the time he releases the first official final screenshot of the new part to the date the game is released.
Therefore, apart from the possibility I mentioned, I'm inclined to think that the deadline Orb gave earlier (later November-mid December) is when he will publish the first final screenshot of the new part, which will premiere around a month later, that is, in January 2026.
However, the crucial thing is that Orb continues to develop the game despite the circumstances, and although for many, that month of possible delay is a serious matter, I believe it is not something to worry about because Orb has demonstrated his willingness to continue his work until the ending he has decided to choose (which I personally believe will be multiple in nature given the different main routes in the game based on the possible choices).
