Not sure if I would use the word dying, but I think the GB is going to do some 'right sizing' and the organization will pull back to a smaller organization of jw zealots, pretty much cull out anyone who is not fully on board - and then in order to gain cash flow, I think new light will eventually come that is somewhat along the lines of tithing.
IMHO they are having issues controlling information flow with the internet, texting and all other methods of communication that are out there. I think there is some risk in the way they are having folks pull down the WTs and Awakes off the JW website, because one could always end up looking at other web pages and information.
I think unless there are disasters which really seem to excite the leadership, hence exciting the rank and file, the growth rate in the developed countries will be stagnant if not negative. Growth will happen in the 'global south' where the cash just is not there to fund the orgs bank accounts.
