I've noticed there's been a lot of talk about the future of the Watch Tower recently. My personal fear is this: In the near future (within 1-2 years), there will be some sort of "tribulation" and the "end" might seem to be very near for JW's. Right then is when the GB will announce that the "Great Tribulation has started" and they will tell all the faithful ones to partake of the "kool-aid". Then the end comes...for them. And then things resume in the world as they were before. There are still quite a few solid, faithful JW's who might partake of a "kool-aid" of some sort without really thinking about what they're doing.
Realistically, I think it's going to be a slow, painful implosion... one with members continually being disillusioned that the "end" never came in their lifetime, resulting in the ultimate loss of faith in God.
