It seems possible, but my theory is that they're pushing 1914 (and the "100 year aniversary") so hard as a positive thing to keep people from realizing that it's been 100 years of nothing but failed predictions and bad medical advice.
I think after this they'll stop talking about 1914 for a while. Then they'll go one of two ways, either start to draw the parallel between Noah's 120 year preaching and the "last days" and start to imply that 2034 will be armageddon. If they don't do that, then they'll somehow shelve 1914 once all the people who remember the days of "1914: The generation that will not pass away" and the like have died off. I don't see them officially noo-liting it out of existance, they'll probably just go to a differernt definition of generation that gets rid of the deadlines, perhaps using other bible passages to imply certain future dates.
By the time they're rid of 1914, they'll have finished the transition to a fully emotion-based message. Gone will be the days of deep study and pseudo-logic. It'll all be about the love in the org and staying away from the evil worldlies.
