It will be smaller but steady, no mass exodus or anything like that. Growth will perhaps decline or level out, with many of them being born ins. More Hall sales along with less Hall buildings, resulting in longer commutes for most congregations sharing a hall with 4/5 others. That won't matter though because video streaming of all meetings will be opened to the public. (It's already available, but by login only.) That, along with JW Broadcasting will be the meetings for many, with attendance 'required' only at periodic gatherings, in addition to the Circuit Assemblies, (which will start using videos in the program and replace the Regional Conventions, resulting in more income instead of spending donations on civic center rent.) The Awake! will be discontinued, replacing it and the public Watchtower with a new single periodical for the public. (The study Watchtower will still be used at weekend meetings.) Once everything is squared away financial-wise, they might foray into real television broadcasts that actually reach people who arent already JWs, (unlike jw.org and JW Broadcasting, which are pretty much only used by members) like Jimmy Swaggart now has. Or they may try to release one of their movies theatrically, (considering the two most recent had improved acting and SFX but also a generic feel good low budget inspirational Christian film feel and message, kind of like the ones the baptists have been releasing). The message and dogma will soften, although they will retain key elements that make them feel unique, like no Christmas/Halloween, no hell, no cross, no war/politics. Conscience matters will become more common. They will continue to have the apocalyptic scare messages from time to time along with light scriptural references to 'prove' a thing here and there, just to keep the rank and file feeling legitimate about their religion, but by and large the message will be a non-confrontational one of standard Christian values preached by many denominations, save for swapping the word "heaven" for "Earth". Most will be content to raise their children this way and pass it on as a fond heritage, based on feelings more than actual details. Besides a major medical breakthrough, I see no solution to one major thing: blood transfusions. This is the one doctrine of many decades ago that would easily have been discarded by now if the repercussions weren't potentially so great.
