Whatever it is, I'd be surprised to see JWs leave the Watchtower in any significant number. Some will claim the news is fabricated by "apostates", while others will say it's a "time of sifting". Others will say that "Jehovah will clean it up in his own time". I think only people who are already on the fringes of the org will actually leave. The society probably has already sent a letter to POs to be read to the congregations, as they did here in Canada just before a prominent child abuse trial started.
We should assume the society already has a response prepared.
