The latest volume of Biblica has an excellent article by H.G.M. Williamson evaluating the proposed Oxford Hebrew Bible project. In the article, “Do We Need A New Bible? Reflections on the Proposed Oxford Hebrew Bible” (Biblica 90/2  153-175), Williamson begins by noting his general methodological agreement with the project, but then continues to raise some very serious problems with the project as a whole. Some of his objections relate to the nature of the textual evidence for the Hebrew Bible, while others are connected with the proposed format of the OHB.
Here is his concluding paragraph:
It shows a sorry lack of understanding about the fact that our text is a linguistic hybrid which makes this enterprise flawed from the start. Its form of presentation only aggravates that problem, since against its stated objectives it will not present anything remotely resembling an eclectic edition of a supposed archetype. And finally it fails to take into account the ways in which the textual criticism of the Hebrew Bible inevitably differs from that of most other texts, leading, I fear, to further confusion on the part of those who are not already well versed in the subject. In the present state of knowledge, as well as in the light of the extraordinary range of diversity of opinion in this field, what is required is full and sober textual commentary. I have no doubt that that aspect of the project will be welcomed and widely used; but it is not a Bible, new or old.
I too have had a number of methodological questions about the project, so it is nice to see Williamson raising some of the same concerns I have had.
I encourage you to read the article carefully!
