Realistically little enough is likely to actually happen. I'd be incredibly surprised if it did. It should, large numbers of the clergy should end being locked up, and a large law suit should be brought.
It's possible a big collective suit could end up being brought, some have already been settled by the Archdiocese which were brought by some victims against specific priests.
I think the churches role as a part of the fabric of the state and society here is going to finally collapse. Priests and monks and nuns have all but disappeared from schools run by the church here long ago. The prpoblem is that the church ran certain public services here for the government at a very competative rate, certainly more cheaply than the state could have run them itself. The hidden cost it turns out was too horrific to contemplate so things will certainly never be the same again.
