It was predicted a few years ago on here that the CO's would be eventually done away with and the WTS would appoint a local, high up, elder (no clergy class right!!) to do visits yearly at his expense. Perhaps this is coming to fruition. I also suspect that some Bethelites won't go so quietly when they get "laid off" so perhaps the GB is opening up spots for some key people to fill when they leave.
I guess we shall see if this continues to happen on a regular basis.
