I thought Arcadi was put back in along with Del Balso once Giordano was hit? That said he must be in something (halfway house) until 2019 and still cannot associate with anyone who is thought to be in the mafia. I got a feeling things will be over before he even gets out fully.
I think the winter of '17 Rizzuto/Sollecito go on trial. If they get out then this year will get very interesting.
To compound matters it looks like Mirarchi and his accomplices may also be let out of prison in the short future.
