Fifteen or twenty, and only because my parish is a convenient one or two hour drive away for them.
There are more, I suspect.
What's next? Baptisms in Latin?
It's funny you should mention that. My newborn daughter was just baptized in the Tridentine Rite this past Sunday.
I think it more likely that, over time, bishops will establish Tridentine parishes and concentrate those who wish to attend all-things-pre-1962 there.
The current model isn't quite like that. My parish has a 9:00 AM Tridentine Mass and vernacular Masses at 10:30 AM and noon. We have traditional devotions (Forty Hours' Adoration, First Friday devotions, novenas, benedictions) as well, and Tridentine Mass on Holy Days of Obligation.
We all live as one happy parish - there is no need to segregate us.
It's funny you should mention that. My newborn daughter was just baptized in the Tridentine Rite this past Sunday.
As new converts, my wife, daughter and I were baptized on last Holy Saturday in the Tridentine Rite also. - The most beautiful ceremony I have ever been a part of - even moreso than my own wedding 11 years ago.
It may not be very apparent in some parts of the country, but many lifelong Catholics I know are sure of the Church's return to pre-VII traditions.
