The second edition of Carson’s commentary on Matthew just became available this week:
D. A. Carson. “Matthew.” Pages 23–670 in Matthew–Mark. 2nd ed. Expositor’s Bible Commentary 9. Grand Rapids: Zondervan, 2010. 
It’s bound with the commentary on Mark by Walter W. Wessel and Mark L. Strauss (pp. 671–989).
It’s not drastically different from the first edition (1984), but the entire commentary is updated to some degree in both content and wording. It’s about fifty pages longer than the first edition because it adds new discussions that interact with secondary literature over the past quarter-century.
Related: Zondervan also just released a superb commentary on Matthew by Grant Osborne in the Zondervan Exegetical Commentary series, which uses a format that serves preachers extremely well.
Exciting! I’ve been working through Dr. Carson’s 1984 commentary alongside my Greek exegesis class in Matthew this semester with one of his former students, Stan Porter. I’m guessing the treatment of verbs throughout will be updated in this revision? I’ve got some notes in my analyses to go back through his revised version and see if the discussion is updated. Much appreciative of Dr. Carson’s work and looking forward to yours on the Logos platform very soon. Blessings.
Thanks, Andrew. And you’re right: Carson updates how he handles verbal aspect in the second edition.
Exciting! Any idea when the revised expositor’s commentary will be available through Logos?
No. Sorry, David! (I wish that all good commentaries would come out in Logos at the same time they come out in print.)
Just reading the preface to your work now… something tells me I won’t finish it tonight.
Congratulations!
