There have been many comments flying around alleging that there are no old rite Masses in Argentina apart from those offered by the SSPX. It seems that things are different. Clarin.com reported that 48 hours after Pope Benedict issued Summorum Pontificum, Archbishop Bergoglio arranged for Mass according to the usus antiquior to be said regularly at St Michael the Archangel in Buenos Aires. (Source: Clarin.com: Regresó la misa en latín, con mujeres cubiertas por mantillas)
There is also a google map of places where Mass is said in the old rite in Argentina according to the provisions of Summorum Pontificum. (i.e. not the SSPX chapels in Argentina but regular chapels either diocesan or religious.) Una Voce Argentina also has news of Masses celebrated in that country.
Unless these sources are all completely bogus, they do scotch one rumour that seems to be taking hold. I have seen bald assertions in various places that there are no old rite Masses in Argentina except those of the SSPX. That is wrong.
It may be that Cardinal Bergoglio was not personally enthusiastic about the usus antiquior but as a Jesuit who exercised authority, it seems that he was loyal enough to implement Summorum Pontificum. Let us pray for him as he enters the world of papal liturgy which may be a different experience from the liturgy celebrated in many places in Argentina. Let us pray especially that he be given the grace of state as he begins his ministry as the successor of Peter.
