I would venture a guess that this will be a Sonnerie movement that is new to Patek. When the 5520P came out people were all surprised that an Alarm dual time watch was possible in a Pilot case. Well, this time the Calatrava(looks like in the pic) will have an either Sonnerie or Petite Sonnerie movement... that’s my guess. The price for the piece will be in the mid $200k range similar to the new price on the 5520P.
