The Vatican has announced that the new English translation of the Roman Missal will be implemented in Advent 2011. GetReligion looks at coverage of the story. See also the USCCB page, especially the Order of Mass. It’s a more literal translation, with both the imagery (and the theology of sacrifice) much clearer than in the dumbed down version used since Vatican 2.
One of the consequences of this retranslation is that all the musical settings of the mass that Catholics have become accustomed to will no longer be able to be used (at least officially). Look for a plethora of new settings and new hymnals in the months to come.
