First time poster. In my cong (Northern part of Europe) we will also be watching this on the service meeting on the week of sept 21. I have not heard a letter read to the cong about it, but I try to miss the midweek meetings as much as I can. As much as I don't wanna go that day, I think maybe I will, just to have a look at the faces of the others.
My guess is they want to make sure everybody gets this real "important" message, including the ones that are not regular watchers of tv.jw.org
