Pope holds extraordinary consistory today with Cardinals and soon to bes

Not a big follower of Fr. Thomas Reese, SJ but he had a nice explanation of the "extraordinary consistory"

There are two kinds of consistories. Ordinary consistories are normally for certain solemn ceremonies such as canonizations, the conferral of the pallium to archbishops, or the creation of new cardinals. For an extraordinary consistory, the pope calls all the College of Cardinals to Rome to advise him on issues facing the church. The discussions in extraordinary consistories are not open to the public or media. 

An ordinary consistory to create cardinals will be held on November 20; the extraordinary consistory will be held the day before. This is the same pattern Pope Benedict followed in 2007, when the cardinal designates were allowed to participate in the extraordinary consistory before they were made cardinals the following day. At a Mass on the day after they became cardinals, the pope gave each a gold ring. Scheduling an extraordinary consistory before an ordinary consistory is simply a matter of convenience since so many cardinals will be in Rome anyway for the creation of the new cardinals.

When I heard extraordinary, I was thinking some traditional liturgy or ceremony.  Although, I'm sure traditional liturgies might just be one of the subjects being discussed.
