If you think about it, it's kind of genius - JWs will lap this up like a hungry kitten being served a plate of warm milk. They'll do the same sort of calculations & inferences I just made above and run with it. It will get people all psyched up and convinced that the GT really is "imminent".
Yes, the dubs will take it hook, line and sinker. I don't how genius it is though. It's just another delay, they didn't solve anything. I guess the genius is that they've put it out far enough that they won't have to worry about it in their lifetime. Let some poor annointed sucker in 2080 worry about it.
And all of that without pointing to a specific date - there's nothing there that can embarrass them later.
No, no specific date...but it does tie one generation back to the other which has time limits. If this comes out in print, it will come back to haunt them in a couple of decades. When the other annointed start dying off, someone's going to point out that they were wrong yet again.
I can't see why they just can't bite the bullet now, divorce themselves from all things 1914 and 'generation', take their losses and re-market and rebuild after the fallout is over. All they ever do is delay it. Maybe they really do believe the shit they're shoveling.
