A new series from Zondervan is out (Obadiah and Jonah volumes have released). I'm reading through the Obadiah volume at the moment, and it's pretty good so far.
With a couple of exceptions, this is more or less the OT counterpart to ZECNT, which Accordance already carries. It would be great to see Hearing the Message of Scripture in Accordance, too! The series preface mentions future electronic editions, so perhaps this is already underway. (For those interested, more on the series is here, via Zondervan).
