I would love to see a crumbling and withering of congs. But now with the "great expansion" of building ... I mean ... scrapping kingdom halls I think there will be amalgamating of congs. In larger towns and cities every 3 to 5 average congs can easily be made into 2 or 3 larger congs. That means less platform work for the Elders and MS's, less CO's needed. So the desperation for "brothers reaching out" is reduced in the short term.
Imagine 3 congs with a total of 20 elders - well that can be two congs with 10 in each.
The good thing is more chance for faders to go less noticed under the radar while the elders fight it out for the prominent jobs and take a while to settle in..
