Any changes of doctrine will be trivial items that will largely go unnoticed and mostly not understood or cared about.
I cannot see any major changes such as dropping 607BCE which would wake up too many if they admitted they had had this date wrong since they changed from 606BCE back in 1943.
The investment in Ramapo and such shows it is going to be a digital future and selling KH's and AH's will speed this along.
I may be too old to see many of the changes but they will come.
