A few years ago, when we attended the Society chapel in Chile, the English speaking priest mentioned that their customs were changing because of 'the Frenchies', as he called them, and they HAD to comply. "Lots of changes coming" he said.
The Leonine prayers only offered by one priest after Low Mass prompted me to ask him. However, they did not remove the chasuble, and I've not witnessed it yet in other chapels.
