The NA29 and UBS6 will be coming out later this year. Houghton has updated Metzger's (and Omanson's) textual commentaries to match the UBS6 apparatus. I certainly hope that Logos plans to release this as well. In the U.S. it will be handled by Hendrickson. William Varner (The Master's Seminary) already received a print copy of it (directly from Germany). Amazon will release this in print in November.
