I doubt they have a ten year plan, five year plan, or any plan at all. They just react. I expect more changes pretty soon; practically anything is on the table. I think it would be easier to identify things that they most probably will not change.
What they won't change, in my opinion:
Core doctrines like use of name Jehovah, the name Jehovah's Witnesses, soul sleep, eternal life on earth, non-trinity, war neutrality, general congregation organization (elders, ministerial servants), circuit overseer arrangement, an emphasis on recruitment/preaching, I'm sure I've missed some.
Anything outside these sorts of things is on the table for change.
