I don't think the Watchtower will give up the list come hell or high water. Nope, not gonna do it. That would cost them way more than any fine the courts could ever impose on them. Even if they said pay $10 million if you don't give us the list, I don't think they would do it.
So I think they will just go ahead and default on the case and call this one quits. I think if they release the database it will open up lawsuits in the tens of millions maybe 100's of millions because of the damage and backlash that such a database would up everything up to.
