Having studied and made lots of projects on the GT and the Big A when I was in I always understood that during the GT some of JW's would fall in death but as a whole the organisation would survive...thus those who did die during the GT would be resurrected quite soon after the Big A had ended.
But recent articles point to the scripture that says that he who endures to the end is the one that will be saved and the GB say the end starts with the GT which indicates that not one JW would die during the GT which then makes any trial during it pointless.
Now that I am out there is simply too little detail in the bible to get any detail and therefore the GB are making it up...
