Latest information on the Instruction, from Messa in Latino:
Great concern was raised in the Traditional world (and in Roman dicasteries...) by the leak of news of which we have been the co-authors, along with Rorate Caeli, regarding the contents of the Instruction on the motu proprio; for which we have spoken openly of the watering down of the motu proprio and have promoted, along with the New Liturgical Movement, an international appeal. How much the latter may influence matters is unknown; but we do know with certainty that what was set in motion, thanks to our sources (honestly concerned with the fate of the Church and of Tradition), has indeed made the Holy Father discreetly receive requests of the very highest levels regarding this famous Instruction. The Instruction is ready and Cardinal Levada, Prefect of the Congregation for the Doctrine of the Faith (and President of the Pontifical Commission 'Ecclesia Dei'), discussed its final details in his audience with the Pope last Friday; but some amendments are perhaps still possible.
