I am not so sure an organizational "collapse" will equal JW's beliefs automatically evaporating. The behaviors, (such as shunning), are likely to endure for some time, as these are not only deeply ingrained, but also a product of the cognitive dissonance they experience. While the failure of the religion itself under a purely rational analysis, should make someone rethink their actions and behaviors, human nature simply does not work that way. They were JWs for a reason, and that underlying reasoning, (no matter how flawed), does not necessarily need an organization to exist. That said, I think those already "on the fence", will likely fall on the right side of it.
Those that I care about, (so not everyone), that fall on the "right" side, will find me waiting for them. The others are mere former acquaintances.
