NO.
They will just stop talking about 1914, and after a while everyone else will stop talking about it too. The Watchtower is getting out of the prophecy interpretation business, slowly but surely, Revelation book study notwithstanding. I suspect that was probably at the behest of one of the oldtimers on the Governing Body.
I think as time goes on we'll see them focus more on their current strengths--control, loyalty, and retention.
I will morph my opinion out of this- I truly believe they would like to stop talking about 1914, and this has been considered.
The problem stems from their need to give weight to their authority. They hitched their wagon to 1914-1919 fulfillments, now
they live with the hitch. They unhitch a bit at a time. They got "this generation" off of a 1914 countdown. I expect that they
will very shortly tighten up on the remnant, forcing the numbers down, then we can better speculate how they will proceed.
Here's my thought, though. Everything is about membership numbers growing and contributions flowing. As they develop
these ideas, the numbers continue to go in the toilet. They got 15-minutes-per-month elderly publishers to keep their
numbers high, teen baptisms, more efforts in third-world countries. It's not working. Someone will eventually examine the
results of 1925, 1975, and say "The fallout afterward was smaller than the growth before." They will develop a new line of
thought on 2034, with time to develop it into a panic like 1975. This will start after the numbers really start plummetting
faster- when the current JW drones get tired of "The end is right around the next corner." Perhaps this will start after 2014.
Their words will be so calculated that they never said anything 100% definite, but everyone will believe it's definite (like 1975)
and they will also develop the fallout strategy beforehand (like 1975) in an attempt to retain members. This will be more than
a recruiting campaign. They will need a serious retention campaign. That's why I am pretty certain it will happen. This effort
will ultimately fail in recruitment, but make great strides in retention (for awhile), allowing them enough profit to make it to the
next focus.
They may go back to Freddy Franz's nutty 7000-years Creation Day, again, after that. I discussed at length why they never
needed to abandon this, entirely. If Adam was 130 years old by the time Seth was born, then the creation of Eve, the sin in
the Garden of Eden, the birth of Cain and Abel- ALL THAT- must have happened within 130 years of Adam's creation. That
gives 130 years after 1975 for the first 6000 years of the 7th day to come to an end (minus time for 2 births- say 128 years). That gets them past the year 2100. IMO-
that will be part of their fallout recovery over 2034. (Complicated? Try reading F. Franz's other theories.) They will think all
this nonsense will bring them back to their heyday.
