Yea, so I missed this comment at the original post on the Collins NRSV with Grail Psalms to be published in the UK. Thank you Sam for the following info.
Hi there, I'm the editorial director at Collins, I can confirm a few points about this Bible. It will contain the current versions of the NRSV and the Grail Psalms that are used in the UK - if and when CBCEW approve revised versions for a new lectionary (as is happening in the US with the Grail Psalms and in Canada with the NRSV) then we will update this product accordingly. However, as the timings on this seem rather up in the air at the moment, we have decided to push ahead with this Bible now, as our survey data suggests catholics in the UK are now mostly buying NRSV for their personal study rather than JB. The Grail Psalms will be added at the back rather than in place of the NRSV Psalms.
