I think that later on you may see a subscription service to the JW.org for all the literature. Some free for the public. Most magazines do this already. So if you want the truth as revealed by Jehovah's appointed faithful and discrete slave you must pay to subscribe.
Also as mentioned in many post in the past is the fact that the org is getting older. At the last RC in USA, my location, I could not help but notice that in 10 years maybe 30% won't be there and in 20 years 70% gone. I'm sure the WTBTS knows this and has a plan to address the issue. I would just like to know how. It should be simple marketing but the geniuses on the GB with all their marketing knowledge and education just don't get it.
Not talked about much is the fact that there are organizations within the organization. Minority groups, cultural groups that are currently (that appear to be) assimilated in the org, would easily leave if things changed from a doctrinal stand point or better yet someone with charisma who is high up and from the same cultural. Take away the kingdom halls and this would happen fast.
I don't see the government going after them (WBTS) but rather a crumbling from within.
