The chief editor of religious matters for the semi-official daily newspaper of the French Catholic establishment, La Croix, [Father] Michel Kubler, a very well-informed religious journalist, has some interesting words in an interview to the Croire website, though he does not specify any source for his information:
...the reintroduction of the Rite of Saint Pius V, the rite of the Council of Trent [30(sic)] must be expected, [though] it is not yet known under what form neither after what time[it will happen]. This rite would be reintroduced along with that of Vatican II. Every priest who wishes to celebrate this rite will be able to do it without a specific authorisation from the bishop. Today, the celebration according to the rite of Saint Pius V is strictly regulated. The new dispositions which Benedict XVI would like to make public, from now [up to] Christmas undoubtedly, would state that every priest may celebrate this Mass and that every community has a right to it.
