I hope the Protestant megachurches, Reformed and Orthodox enjoy their uptick in membership. /Sarcasm
Because while some will go to the traditionalist groups, a lot won't. They'll just bounce from Catholicism, entirely.
Worse than that, you'll see the sspx people and the indult people staying exactly where they are. They will continue to scream at the top of their lungs that this is the Roman Catholic Church. The Catholics have truly gone mad.
