I don't forsee major shifts in doctrine - but 'new light' tweeks and organizational structure changes will continue.
The statement made in the Nov 2013 Watchtower Study Edition ('Seven Shepherds, Eight Dukes' article, par. 17) about preparing for the coming attack of "the Assyrian" and that all need to obey the direction from "Jehovah's organization (that) may not appear practical from a human standpoint. All of us must be ready to obey any instructions we may receive, whether these appear sound from a strategic or human standpoint or not. " should be a cause of concern for every Jehovah's Witness.
When the new World Headquarters completes the move to Wallkill, I suspect the preaching message will change from one of comfort to one of 'righteous condemnation'. The emphasis on 'preaching' in public places with carts, tables, booths, JW.org stores and JW.org trucks brings us out of the deserted neighborhoods and into the face of the public.
"Bring on the persecution so we can prove our faith" will become the new mantra.
