I'm expecting sisters to receive greater 'responsiblities' or 'priviledges' in the very near future. Women are constantly seen in WT videos doing building work. Giving the 'girls' more equal footing in the congregations will make the Org. appear progressive and 'balanced'.
It would be a selling point to new recruits and will help to keep young ones 'in'.
I can see women handling microphones, the sound booth, working the lit/mag/territory counter, managing hall care - inside and out, etc. in the next few years.
