It's been mentioned already, but there is no need for them to get rid of 1914. Not now. Not ever. The new spin on the generation teaching is that a "generation" is an undefined length of time. A generation could be two or three hundred years if you look closely at the way that article is worded.
If they decide to change 1914, it will be because some new "oracle" figured out a new algorithm that sets a new date or deadline for Armageddon, not because they've painted themselves into a corner. The already walked all over the wet paint in 1995 with the "generation revision." They're out of that box already.
