I keep wondering the same thing myself lately.
With the May 2007 QFR releasing the bonds on who can be "anointed", I really feel there's going to be an increase in the number of partakers year after year.
And I know several Witnesses right now who understand that the "anointed" are the ones who take the lead for JW's. We all know the reality.
But with the upcoming June 15 WT, the GB is taking tighter control to make sure all JW's know who's in charge. This may cause some dissension among the younger "anointed" members, feeling left out and under-appreciated. They're not going to have any more say-so than members of the Great Crowd (they never did, but now it's in print).
If there were a revolution, I don't know where it could lead. Would JW's, on their own, examine the Bible without Watchtower-colored glasses? Probably not. They don't do so now, and unless they want to, they probably won't.
It would be very interesting to watch, though. Good enough to sit back and watch the show with some popcorn!
