ICEL has made publically available text and music for the new Roman Missal. There’s is a good bit of attention to detail in the materials. For example, notice in Credo III the way three notes are given to “one” God.
Of course, as they point out:
It is important to note that the texts and music available on this site are for study rather than immediate liturgical use as definitive versions will not be available until the Bishops’ Conferences have determined a date for the implementation of the Missal.
I hope that date is determined soon!
