Prior to the latest generation teaching, I was inclined to think they were looking at putting 1914 on the backburner. Maybe Adventist style where they believe the last days started in 1844 (or whatever) but again the problem is the appointment in 1919. They can't drop that because they will lose the designation of "God's Organization".
But now that they've changed to the crazy Jesus meant two very long, overlapping generations by saying "this generation" I think they are fully intent on keeping the 1914 date.
They will eventually need to drop it or make it mean something a little different but may opinion is that we're at least 20 years away from that. A new "generation" of GB members will be left to make those changes.
I think it's actually pretty funny watching the twists and turns of "logic" to attempt to patch up the crazy prophesy legacy of Freddie.
