We have had other threads on this subject - and generally the concensus has been that a very small percentage - probably not more than 25% actually believe that the new system will come during their lifetimes.
Many, of course, will SAY they believe it - but I think that very very few actually still do.
Here is a typical comment - from the thread on 1975 - and I think it is very true:
Frankly, for most JWs (except perhaps the newest recruits) I think 1975 and the time hence has indeed been "enough". Locally (almost) NO ONE is living as though we are in "the Last Days". Apathy is abundant. Most are going through the motions, not knowing what else to do.
