Over at Evangelical Textual Criticism there is mention of the upcoming publication of the Greek New Testament by the United Bible Societies — the UBS5. I’m not sure of their source material, but it will certainly be a welcome:
Preparations for the fifth edition of the United Bible Societies’ Greek New Testament are underway. These involve revising the choice of variants from the fourth edition, again with the purpose of focusing on those that are most significant. UBS5 will also be informed by work on the ECM. They have written to a number of scholars asking for suggestions as to changes in the variants registered. Although they haven’t thrown the net wide open for comments from anyone, I’m sure that unsolicited but reasoned feedback on this issue would be gratefully received by the German Bible Society, who appear to be coordinating this project. Since they are also planning to have an Additional Meeting at SBL in San Diego, that would be another opportunity to present the editors with constructive suggestions.
