Not much will change. The "busy work" will continue as they continue to declare that The End will come very, Very, VERY soon. There will always be a disaster, disease, insurrection, war/conflict to use to ramp up the message.
I think the CSA lawsuits will taper off, as WT really has implemented new policy to stop the abuse. NOT because of any ethical reasons, but primarily to stop the financial bleeding. WT Legal directs that law enforcement be notified (IF the State mandates such, and perhaps even if not).
I think they will concentrate very heavily on younger members to make them feel important and appreciated (especially young boys/men, less for girls/women who are clearly not as essential) to keep them from leaving.
The donation system -- the mandated per diem contribution for each publisher -- will go up, and up for the congregations, assemblies, etc. Congs that fail to maintain their required donations will be considered for dissolution (after a remodel is completed with free labor).
Conventions will be smaller to make use of Assembly Halls (already happening) so as to avoid paying rent to outside facilities. Locally, they have only one "large" Regional Convention (vs 2 or 3 in the past) and a smaller public venue, while the majority are assigned to the Assembly Hall. So that it does not just seem like the Circuit Assembly, Congs are not assigned by Circuits. Rather, 1 or 2 Congs from each circuit that uses the Assembly Hall are assigned to a convention so there is a feel that it includes a wider spectrum of delegates instead of the same old group at every Circuit Assembly. (This also allows teens to meet marriage mates from other circuits.)
Most changes will be implemented for one of two reasons: Cutting costs or increasing donations.
