The videos from May’s conference are now available here.
The one I would most recommend would be Tod Harris’ discussion of translation. (It is part of the panel discussion, beginning at 41 minutes in.) He presented all sorts of interesting information about how the Church handles the translation of the Book of Mormon into other languages. Phil Barlow was very provocative; he pointed out what he sees as some of the dangers of a project like the BYUNTC. Eric Huntsman was his standard brilliant blend of charisma and scholarship.
