I guess I'll be the first to testify that there certainly is an increase of Latin, and it is largely due to the influence of the TLM becoming more wide spread. The FSSP is the biggest reason for the growth in the number of priests offering it, especially around my part of the world. Even the diocesan priests who offer the Traditional Rites take training from them. And from there the resulting activities bring in more exposure to Latin.
I went to a Gregorian Chant workshop 1 or 2 years ago, which is now annual, and the professor teaching us said "A lot of people don't know Latin anymore even though so many used to understand or speak it. Well, we need to change that and be the ones to make it change by learning more Latin."
He was visiting from Florida, his last name was something like Schaeffer. A really great speaker and conductor in my opinion. He had us all doing polyphony by the end of the day!
Latin is coming back and so is tradition, dont doubt it!
