Apologies if this has been floated out there in this or any of the other Annual Meeting threads, but I found it interesting that they specifically excluded Russell from the FDS.
I wonder if this might be a first step in explaining away some of Russell's more bizarre ideas (e.g., using the measurements on the Egyptian pyramids to calculate Bible prophecy). Arguing that he wasn't a member of the FDS would allow them to disavow many of his teachings.
As a vaguely related aside, I was a litte surprised that the article in the back of this month's Study Edition WT included Russell's pyramid timeline graphic from Studies in the Scriptures.
