I'm pretty sure that if there were 'new light' on the subject we would all know about it.
I think most JW's nowadays are somehow related to someone who has been DF'd or DA'd. I know quite a lot of so-called 'staunch' JW's who now have DF'd teens or grown kids, including elders, PO's, CO's etc. The reactions to the DF'd ones vary. Some still visit their DF'd relatives regularly, babysit their grandchildren etc and are totally involved. Other's completely shun them and constantly pray that they will one day return - they wait for this moment before they can enjoy contact once again. So sad.
