Carlo becomes an FBI informant in the final episode and I believe that Larry is in prison or house arrest. So the new boss would be either Patsy, Paulie or Albert as they are the only capos left. Patsy is capo of Tony/Paulie/Christopher's crew, Paulie of Aprile crew and Albert of Barese crew, but we don't know who is the new capo of Altieri/Gervasi crew and the Curto crew.
Oh right right. sorry i forgot that about carlo plus wasn't there the chance he was helping NY? Albert is a good point too. They lost so many guys in such a short time it would be a hard rebuild
