I think it's very unlikely that they would do it.  For strategic reasons, they need it there.  It keeps traditionalists where they can see them.  My point is only that the answer to what you would do if that happened, would be a good indicator of where you stand.  If you would go with the novus ordo in order to maintain obedience to the Pope, then I would say that you are a conservative Catholic (not that labels really matter).  If you would go with one of the above-mentioned societies, then you're a traditionalist.  If going with one of those societies is what you would do, then you will have to justify your move, because disobedience to authority must be balanced with grave reasons for doing so.  It is not ok to just disobey the Pope, merely because of a sentimental attachment to a liturgical ceremony.  Traditionalists recognize that the new mass is no bueno, and that it leads faithful Catholics directly out of the Faith, diminishes belief in the Real Presence, and puts forth a new, man-centered religion.  Traditionalists hold firmly to the Latin Mass because it is faithful to Tradition, is valid (without doubt), and the priests preach orthodox Catholicism.  Which side do you agree with?  Do you go to the Latin Mass because the novus ordo is a protestan-catholic hybrid religion, which is offensive to God?  Or do you go to it because you think that the old Mass is beautiful?

Icterus, I'm curious as to if you've yet looked at the Father Luigi Villa material yet.

I should reiterate that he was given a mission by Padre Pio, and a commission by Pope Pius XII to expose ecclesiastical Fɾҽҽmαsσɳɾყ. It was by the Pope's insistence that he make his publication entirely independent of the Vatican, so that he could publish without fear of censure or suppression.

Please do read Father Villa's life, and then that thread I linked if you haven't already.
