Cardinal Hoyos sentiments aside, the traditional Latin mass and sacraments aren't coming back in any meaningful way any time soon.
A priest doesn't just wake up on Monday morning and decide he's going to say Latin mass the following Sunday.
It takes both skill and time to learn the chants as well as the particular movements and rubrics that the priest must perform. And considering the vast majority of priests don't know enough Latin to read the slogan on a pack of cigarettes, it will take a considerable time to just get them up to competency in the language.
If Hoyos et al are serious about this, they have to begin by making a mandate to the seminaries that no one is ordained unless they are fluent in Latin and are able to say Latin mass when needed. Even then it will definitely take many years to bring back Latin in a meaningful manner.
I got news for you.
The vast majority of priests who said the Tridentine Mass prior to 1962 didn't understand one single word of what they were saying.
