When I was a kid I used to imagine that the gb went into a quiet room where God spoke to them and told them what to put in the magazines etc, I was very disappointed and rather shaken when I learnt that they vote on it.
I can't see them dropping the reporting of witnessing hours since that's how they identify weak and faded ones. But I can see the 14400 being changed, I note that a number of people here have reported that in the memorial talk there was a mention about the partakers increasing.... maybe that was a stuple hint?
