Where did you get that Marco D'Amico is the over all boss? I know Scott Bernstein (mcscott) has said D'Amico may be in the administration but that hasn't been officially confirmed yet.
With Marcello and Lombardo out of the picture, and now Sarno, you've got the other two old standbys - DiFronzo and Andriacchi, though they're both getting old and there are rumors about the latter's health.
