It seems they're going all in to get Pizzi or anyone close to him...
I figure he'll be dead before the new year or people will have taken over his interests.
Good possibility, December is usually a busy month for the hitmen.
You suppose they get a Christmas bonus?
As for Pizzo, I think that he might be some a sort of street boss for the jailed leaders of the old Rizzuto group who are still holding ground. They probably still have a crew of loyalist who pose a threat to the group trying to take over. I figure the restaurant set on fire might be their work and a message to the usurpers who in turn sent a message back by firebombing Pizzo's business.
Could it really be back to the basics with the old Rizzuto group aka Sicilian faction against the old Cotroni group aka Calabrian faction? With the latest developments it definitely seems like it.
