On the topic of 1919, I'll repost what I said in another thread :
I don't think they really need the 1919 appointment, honestly. I'd be willing to bet that 90% don't even know the significance of 1919, nor do they care. They've already been doing without it in spirit for years. Here's how it works:
1. JWs are the only true religion (they're the only ones known for d2d work, they have brotherly love, etc, etc)
2. God is a god of organization (twisting the scripture "god is a god not of disorder but of peace")
3. Obey those taking the lead (Heb 13:17)
4. The GB is taking the lead in the organization.
And that's all it takes. The GB is to be obeyed, they don't have to deal with the pesky details of a 1919 "appointment" that can easily be demonstrated as false. Just unquestioning obedience.
I'll add that the small number that do understand the significance of 1919, are made up almost exclusively of those who would be loyal to the organization through anything anyway. Removal of 1919 would be a non-event to most, and just another bit of new-light to be accepted without thought to a few. The line of reasoning above is the only reasoning that I ever recall hearing as justification for loyalty to the GB. 1919 is only discussed sporadically when they do one of those "hard" WT lessons on it, and then it's only mentioned off-handedly in one paragraph.
I believe emphatically that the overlapping generations BS is just a stop-gap until they can get rid of 1914. If you've read CoC, you know that they often discuss things like this for years before taking action (they were discussing what to do about the generation teaching in the 70s, but didn't touch it till 1995). 1914 may remain in some form or other, but it won't be the start of "this generation" past 2034, and may well be gone much sooner. The overlap is fairly obviously designed to buy time until those that remember the emphasis on 1914 die off or at least are sufficiently senile or dependent on their JW children that they won't make waves.
The other possibility is that they're just buying time until they die, and they'll let GB 3.0 handle cleaning up their mess.
