In some way, it's going to involve expanded use of videos in weekly meetings. Expect one "Public Talk" a month to be piped in from HQ. There hasn't been a lot of talk on here about the 'new and improved' JW Stream site, but it sure looks like they're getting expanded bandwidth & infrastructure in place to do a lot more live streaming. From what I hear, anyone with login credentials can download regional and circuit events right now in almost any language. Most local public speakers are quite awful, so the R&F may find this a welcome change.
A couple years ago, I thought they were about to replace one of the 3 yearly assemblies with a live stream, but now I'm not so sure about that. Assembly Halls, Regional Conventions, and other circuit level events are HUGE money makers for them. It is possible they may add a 4th yearly 'local assembly day', similar to these streamed 'branch meetings' they've been promoting in the developed world the last year or two.
I don't see how they can reduce magazine production any more than they already have; it's already down to a barebones operation, with one 16-page wide-margined, PowerPoint formatted mini-mag for the public each month, quite an embarrassment compared to what they used to do.
They're between a rock & a hard place in terms of magazine production. It's obvious they would really LOVE to go online only, but their growth model is most productive in less-developed countries that simply don't have as much internet access. If they want to keep growing, it has to be among the least educated populace, as well as 3rd world countries & recent immigrants (their current target demographic), among whom printed mags are often more accessible than the internet. As we all know, these people are coming into the org, but they aren't donating.
This is not a sustainable model. Expect more cash grabs and donation drives, while they tout the need for more KH's in the developing world (and throwing in images of poor JW's in Africa or Asia after a natural disaster).
