I think we're in for some big organizational/doctrinal changes in the next 5-10 years. The wackiness we've seen with the generations overlap is just the start.
The free-flow of information over the Internet is their worst nightmare, and the generation born in the last 5-10 years has not known the world without it. They will not have has much (or any) "fear" in googling their questions as older generations.
And, as much as many doubt it will have any effect, the passing of 2014 will be a tipping point. Time is not on their side.
I mean, be honest: imagine knocking on a door in 2015 and telling the householder you have GOOD NEWS! That Christ has been ruling in heaven for over ONE HUNDRED YEARS! Wow, that is some great news. . .
Not saying I think it will implode, although I hope it does. . .
Not with a bang, but a whimper.
