I think we will find that when it does get dropped it will mean nothing to the average witness, no shock or WHAT! from them. I even think today that most witnesses don't even understand or know the meaning or significance of 1914. Because of this lack of knowledge regarding the importance of 1914 that most witnesses currently have, they will view the dropping of it has just more evidence that Jehovah is guiding the faithful slave. More reason to remain steadfast in this organization.
The reason I say this is because I have tried to help some who are completely wrapped up in this religion see some hard hitting facts about the wtbts and they can't or won't even consider it, and then I get an ear full about being negative towards the organization. Can't get through to them here so very unlikely 1914 or any other changes will wake them up.
