I was baptized in 1967 and pioneered during the late 60's and early 70's, and I can attest that 1975 was just about all anyone talked about at the meetings or in private. When the "Truth" book was released, we were totally focused on starting Bible studies with "right hearted ones"...and if they didn't dedicate themselves to being a JW within six months of study, we dropped them like a hot potato to move on to others. There was an excitement in the congregation and at assemblies that was palpable. I got married in 1971, but was "counseled" a number of times that with the end being so near, I should not burden myself with the distraction of taking on a wife. Every activity was measured against 1975 to classify whether it was folly to pursue or good theocratic activity.
It was an exciting time to be a JW, but after 1975 came and went, large numbers of people disappeared from the congregation. It amazes me that the WTS actually blamed "zealous" borthers for reading too much into chronology. Talk about passing the buck!!
For JW's in 2010, I would say that the those that lived during the events leading up to 1975 are either dead or long gone from the organization. The movers at Bethel behind the 1975 push are dead. In another 20 years, all connection to the events of 1975 will just be a historical memory to be buried in the crypt of old JW apocalyptical dates.
