Also done with my two interviews and just waiting the final decision.
I had a look at last year's thread (there were just three rounds so the final decision was due in December). It seems some announcements were made 2-3 days ahead of the final deadline. If we follow the same trend, we can expect to hear w/c 24/11.
As the decisions were notified by telephone, there was quite a bit of agonising for GMATClubbers between calls!

I also checked in with my AO who said she will let me know the final decision around 28/11 and if she has any news before, she will let me know.
Best of luck to anyone waiting for news!
