Imagine when the new "Overlapping Generation" teaching (along with 1914) is finally dismissed for good. The excitement over new light and Jehovah's loving provision of life sustaining spiritual food at the proper time will be shared by the majority.
Leading up to that will be much less discussion of 1914 and the Generation teaching. Less and less of that over time, leading up to eventually dumping it. By the time they finally get rid of it and announce new light, most people by then won't have much knowledge or memory of these teachings as having much importance because those that do will be from generations that have passed away. It won't rock their worlds. It will be a blip involving "exciting new light" and seen as a wonderful, loving provision from Jehovah.
That's my best guess anyway.
