The good news is that Francis is no fan of the Tridentine Mass. Yes, he did say Mass in Latin in Korea, but that was because he did not know Korean, and they did not know Italian or Spanish. As archbishop of Buenos Aries, Argentina, he forbade the Tridentine Mass in his archdiocese until Pope Benedict mandated that it be available throughout the universal church whether bishops wanted it or not. Francis has never celebrated it (he was ordained in 1969) and never will. He hopes it will fade away.
Nor is he happy with the push for literal translations, including translating pro multis as "for many" rather than "for all." As a result, the Vatican push for new Italian, German, and other translations has been put on hold.
