I wonder if they are going to pick a new starting point, like having Armageddon supposedly happening in 2034. From then, they can build the scene that 2034 is the beginning of the end, starting again from there. Of course, that means they will need to redefine 607 or what "times" actually means.
As for arguing that there are not 7 million witlesses around, I will give it my all. I believe there are quite a few fake time slips among the 7 million. Either they did no field circus at all but turned in a fake slip, or the hounder (under pressure from the hounder-hounder) turned in a fake slip so it would not be missing. There are also a lot of people that are in it because of pressure (if they quit, they will be hounded and possibly never see their family again). And, if you have a baby out in field circus, why not put in an extra slip for the baby to count toward that 7 million?
I would like to see a TCMP style audit on that number. I wonder how many witlesses there would actually be if every fake slip, duplicate, miscounted slip, or slip turned in because of severe pressure or on behalf of small children would be thrown out. I bet it would be quite a bit less than 7 million.
