This Overlap stuff is such heavy crap. I wondered why they had so many changes in the last few years. It might be because the Old Guard is in charge and there is a small Governing Body. The last few guys have been there a few years and have learned the politics, but putting anybody new in the Body would be exposing them to the true way things are done, not by Holy Spirit and praying over the matter until God clearly tells the unanimous body what to do, but rather by dictating and politicking and getting a majority.
While the members of the GB have been the Old Guard, they have made changes such as doing away with the bookstudy in private homes, they have ditched 1935, and now they have changed "generation" in 2008 and a wee bit more in 2010.
Any major changes they still want to do will come fast. They know the men are old and they need new men. They want the new men to be there awhile with minor adjustments so that they start to believe that Jehovah actually resides over their meetings. So if they are done, expect to see new Governing Body members appointed. If they are not done, it won't happen.
