Past evidence shows what is likely here. I know this doesn't have anything to do directly with music, but corporations have taken over the government. They insist on having the same rights as a human being, yet when it comes to punishments they know they can get away with murder.
If I had attempted to root kit even a small fraction of the PCs that Sony did, or commit copyright infringement on a much much smaller scale than what this story talks about, I would be ruined. I would lose all my possessions, probably be thrown in jail, unable to contribute to society, and disconnected from social ties. But we all know that these record companies won't be drastically hurt by this. Besides, the executives have already given themselves bonuses and spent the money on blow, or whatever else it is that these people spend millions on.
No one is going to jail over this. The industry will not be hurt. And no lessons will be learned.
