Wallace announces the release of two DVD:s on the Parchment and Pen-blog here (includes order info.).
One contains his plenary lecture at the Evangelical Theological Society’s annual meeting: “Challenges in New Testament Textual Criticism for the 21st Century”
. . . and the other a lecture on whether our Bibles today essentially reflect the wording of the original text “Is What We Have Now What They Wrote Then?”
I think I heard from someone that he mentions this blog in the first one (the plenary lecture at the ETS meeting). Maybe someone can confirm that?
