Good news, interview has been scheduled for December 12! Incredibly fast!
I decided to check the myUSCIS account today, despite not getting a "We have taken action on your case" email, and was surprised to see that they had scheduled the interview as of November 8! Best part is the the notice with the appointment details is available to view there in the account, so we don't have to wait for the mail.
Strangely, it's still estimating 9 months for a case decision (up from 8 months last I checked).
