Rorate Caeli dug up an article today from Panorama in Italy which further speculated on a few matters, not the least of which the, as yet unsubstantiated rumour, about a possible papal Mass in the usus antiquior. To date, this speculation has remained quite vague and has not seen any clearly evident curial speculation that is at least public.
A twist that this speculation brings to the table is the idea that such a liturgy would occur not in St. Peter's Basilica, but the Basilica of St. Paul Outside the Walls. We shall see.
