I can't see that FS will end.
1 - It's such a big part of the activity of witness and is used as a measure of spirituality.
2 - To reduce the preaching work would counter the use of "this good news of kingdom" as a sign we are in the last days
3 - It creates a difference with pretty much all other religions and is therefore used as an identifying mark of the "true" religion
4 - To annonuce a complete end will say Armageddon is iminent and that would be organisational suicide unless they really knew something we didn't
5 - It would mean the videos and pictures in the magazines showing 1st C Christians going round with a bag and scrolls D2D would be out of date
I think the more likely scenario is that the form of the work may change. We are seeing a move to online only material, the size of the magazines is decreasing and there are now at least two leaflet campaigns per year (memorial, convention) with the possibility of ad hoc ones as well (e.g. the Truth leaflet one). The memorial one is now tied in with the reduce aux hours effort.
Interestingly enough the first year (2011) of the 30 hours aux pioneer effort was very well supported (approx 40-50% of publishers in pretty much every congregation I knew). 2012 was a different story - far less support, around 30% less in our cong and similar figures locally with much less "buzz".
The society are downsizing and reducing costs. The above mentioned changes as well as the move to picking up what mags you need as and when suggest they are much more concerned about reducing waste and costs.
There has also been much more emphasis from COs to place books. My experience has been that the CO is measuring out FS activity on the basis of book placements. This does reflect the chance of getting Bible studies as no one comes into the truth on the basis of WT/A only (or, God forbid, just a pure Bible study), but I think also suggests that perhaps the role of the magazines may be reduced as well. It's cheaper to print a leaflet, get a mass distribution campaign and then follow up interest with a book for example.
There was also this in the recent WT 5/15 p20
15 Continuing in the Kingdom-preaching work in these last days re-quires faith in Jehovah’s timing. The changing world situation may call for some changes in how the disciple-making work is carried on. The organization may occasionally make adjustments to address the needs of our activity as Kingdom proclaimers. We demonstrate faith in the God of “times and seasons” by fully cooperating with such adjustments as we serve loyally un-der his Son, the “head of the congrega-tion.”—Eph. 5:23.
Q 15. How can we show faith with regard to orgaizational adjustments?
This may be referring to the changes already made and general things like promoting studies on the first saturday of the month etc. It could also be laying a foundation for changes to come.
Anyways, it's all just speculation but I really don't see them turning around and saying don't bother going D2D, don't bother churning out forests anf forests of literature, just speak to people informally, use your bible and be a good example...
What really is a possibilty is that the effort to reduce costs the public WT/A will all but disappear as far as the FS is concerned. We will be told to do leaflet campaigns and follow up with books to get straight to the point about bible studies, stopping all these route calls and cozy magazine drops. Net result - less cost, more targeted recruitment drive. I can't imagine that pioneers will be happy - trying to do 70 hours of first call again!
