The WTS/Christian Congregation of Jehovah's Witnesses (CCJW) is no longer in the business of dates!
They have learned their lesson according to the last talk on Saturday's DC Program. They admit the were 'eager' like the Apostles before them.
I know of the talk of which you speak because I had the displeasure of sititng through it. Even so, I can see 2034 become the next 1975, just maybe not as played up as much as 1975 was. There was already a WT study article that hinted at the significance of 120 years from 1914.
Now that my mind is on the subject, I'm surprised that 1994/5 wasn't emphasized more due to the Generation teaching at that time. 80 years is pretty much as long as you could define a generation to be. Maybe they knew it would be doomed to fail anyway.
