Armageddon has always been 'imminent' but has never come, in almost 140 years of the JW religion. More than a few are well aware of that even if they won't say it out loud.
Older ones have been making many comments like this lately. Stating that they never thought they would graduate high school before the end or make it past the year 2000. Of course, they follow it up by saying that is why we must have faith in the resurrection.
