Confusing array of Catholic liturgical options? Good for evangelisation?

I can never quite get what is happening in contemporary Roman Catholicism. One set of headlines implies that a 'new' mass is being introduced (though really it is the 'old' Latin Mass more accurately translated) and once introduced to a country has to be followed to the last consubstantial change. But then there are headlines which suggest that this and that form may be followed ... well let my confusion not confuse you. But head instead to Catholicity and Covenant which has a post on a recent Roman liturgical announcement and an excellent reflection thereon.
