WTS seems to be avoiding the "crash and burn" exit from the world scene. But it gets deeper and deeper in the hole they created and will hopefully not be able to recover at some point.
1. Youth retention. They tried demonizing college and the internet and things young people enjoy. Parents generally cooperated, but the college thing might have been too much. Parents want the best for their kids and might not help, but might not hinder their kids going on to education and out of the WTS.
I see the latest "generation overlap" as 1975 all over again. They had excellent member retention including young ones prior to 1975. Even though their end-date expired, after 1975 they seemed to retain more new members than they would have gotten if they never had the doomsday event. I could imagine their next end-date would be 2034 (120 years from 1914 similar to the 120 years God gave man in Noah's day). They would avoid putting the date directly in print, just indicating a parallel to the days of Noah in the WT study articles and hyping the members at conventions.
I doubt that any effort to retain youths would work. They use the internet and learn about WTS. If they fell for the end date, they would leave in huge droves when the date came and went.
2. Fewer males able to teach. I see them constantly combining congregations. Along with "fewer males" they have "fewer people." They have made it easier and easier on the elders to run things- shortening or eliminating meetings, providing enough information that they don't have several hours of preparation time for meeting parts. I doubt they are ready to let women step up, but they might expand some women's part in the mid-week meeting or allow pre-recorded audio (or even audio with video) for several meeting parts to come from WTS.
3. Science. Not much they can do. I see them ignoring the creation accounts of the Bible and not arguing with Science more and more. But they do have to clash with facts to present their version of the truth.
