I think the org will change as it always has according to the times.
One thing it has against it though is TIME ,after all it is a belief based on foretelling an inevitale ending....so if it does'nt end surely their comes a point in time where the twisting of scriptures must end ,and people will get deflated in faith for that brand of religion .So to survive it must lose it's history and re-invent a new one .In part this has been done for it's hard to get older publications and the JW's are kept distracted and busy with the new stuff and discouraged from reading and questioning the old.
This site like others is a strong weapon along with time to expose the JW religion from with-in and that's where the damage occurs ,I believe , not so much to ordinary folk who hear about them on the news for they are just another religion to them .That's why the GB has always fought so hard to fight any free thinking and questioning by labelling it apostate .
To say they will disappear is a hope only in the short term ,but they will change for they will in time drag up scriptures like this one from time to time and focus on it in their KH talks,Their Assembly talks and literature ,and this will push the rank and file to try again when they feel low on energy.................................

For YOU know this first, that in the last days there will come ridiculers with their ridicule, proceeding according to their own desires 4 and saying: "Where is this promised presence of his? Why, from the day our forefathers fell asleep [in death], all things are continuing exactly as from creation’s beginning."They know their arsenal well and have always used it according to the times,but eventually TIME will defeat the org as we know it today and as it has been.
