Don't spread it. Wait until it comes out on JW news
That is the line for "keep your shit to yourself". I seriously doubt they will ever announce such a thing officially. Unofficial rumors will be quashed in the same fashion as above. If the rumor grows too big to the point that they have to do damage control, they will spin it somehow.
As it is, a JW broadcast was put together to clarify that even when the loans were forgiven, donations were still necessary, what do you think would happen if they officially announced the halting of construction?
