On a few occasions I've heard suggestions of 2034 as the "date", since it is 120 years after 1914; Just like Noah's time.
It looks to me like the Governing Body is being pro-active in preventing this in becoming a date that is speculated on.
The Dec 15, 2010 WT (Printed Version) has an interesting QFR, asking if Noah had knowledge of the 120 years. The answer was: Noah didn't know about the 120 year time period, but that didn't matter to him because he knew it was coming and kept busy. I don't currently have the printed copy handy but can post a few quotes from it later on (unless someone else has it handy).
Just thought it was interesting. It seems to me that having a group of men in leadership instead of an individual prevents any fanciful speculation on dates from becoming official.
