Speculation at this stage - I have heard nothing yet
Speculation as to the content of the meeting or whether there is a special meeting on Mar 7th?
Whether they do have something to announce or whether this is a publicity stunt is yet to be seen. But it is generating buzz. Buzz means people have some excitement and enthusiasm and they'll be talking about it. It's kind of like a mini-1975. For the next month or so, JWs will be speculating, is the end really about to come? Is that the announcement? Oh my, I'd better start being a good JW and get out in service.
Of course, I can do my own speculating. I doubt it's anything doctrinal. Those have usually been handled through the Watchtower. When they changed the generational thing, they did it through the Watchtower. Unless they feel this is a bad aproach, I don't think it's a doctrine change.
Growth in the US was 0%. One possibility is that this is a stunt to revitalize the preaching work. First to inflate those memorial numbers, and then to get some of those memorial people coming back and participating again.
Another thing, as mentioned here a few times is that the Awake may be going to monthly rather than 2 times/month. That's kind of a big change and may require the proper smoothing to project it as a positive thing.
The new blood paperwork just came up. This could be a follow-up. Maybe a new blood booklet for you to give to your doctors.
Or they could be announcing changes in organization, branch offices, etc.
We'll just have to wait and see. If anybody is still attending, please go and report back to us. If it's super-secret, might even be a good thing to tape.
