The Society of Biblical Literature and Logos Bible Software are working together to create a new critical edition of the Greek New Testament. Apparently, it is going to be called the “SBL Greek New Testament” or SBLGNT. (HT: Evangelical Textual Criticism)
According to the website, the new edition is being edited by Michael Holmes, will be different from the Nestle-Aland (NA/UBS) text, and will be available for free download.
Furthermore, SBL will produce a print version of this new edition of the Greek New Testament.
I haven’t seen any information about the text itself. Hopefully, there will be some good reviews and comparisons coming out soon.
