For what it's worth, Ivy is mostly an East Coast expert and there hasn't been many press releases or indictments (typically what Ivy uses when constructing a leadership hierarchy for a family) handed down since Family Secrets that would prove or disprove some of the more popular theories on who is running the Outfit right now. Near as I can tell, the only ones who've been officially confirmed as crew bosses through one of the above sources are Toots Caruso and Albert Vena. The rest are up for speculation, although Burnstein has posted several articles regarding what he views the leadership to be.
