This is definitely an early Christmas present for many.
fatbus, lets go with that.
In reality (not a fact) STC has been playing lame duck role since August, 2015, probably Emir decided he needed to do something. It became more ceremonial when CM joined.
Retired, fired, rumor, truth or fact, who cares as long as there is an expiration date.
Any news on rest of Mafia B and Mafia I, are they planning an exodus or planning to stay put until they are "retired". I am guessing option 2, because they are not employable because they have no real skills.
