I guess things are moving along but who knows when it'll be published. Here are excerpts from the USCCB website:
Revised Grail Psalms
March 19, 2010: The Revised Grail Psalms were granted recognitio from the Holy See's Congregation for Divine Worship and the Discipline of the Sacraments.
After four years of use by some religious houses and review by the USCCB, a series of modifications were proposed.
November 11, 2014: the U.S. Bishops voted to accept the modifications. If confirmed by the Holy See, this new version of the Revised Grail Psalms will be used in the Liturgy of the Hours, Second Edition. They are known for being remarkably faithful to the original Hebrew while also being rendered in a "sprung rhythm" to facilitate singing.
As of early 2018, the modified Revised Grail Psalms are awaiting confirmation by the Holy See.
Old and New Testament Canticles (including Gospel Canticles)
June 11, 2015: The USCCB approves new translations of the Old and New Testament canticles. Prepared by Conception Abbey, these canticles are rendered in the same "sprung rhythm" as the Revised Grail Psalms.
As of early 2018, the Old and New Testament canticles are awaiting confirmation by the Holy See.
