There hasn't been anything "new" in a decade or so. What "new" "literature" there has been, has been updates, rewrites, and condensations of stuff produced in earlier years (rewrite of "Bible Stories" book, rewrite of "Greatest Man" book, condensation of "Proclaimers" book into "God's Kingdom Rules", etc.)
JW reaction?
A shrug of the shoulders, burbling praise of the jw.borg website & its many videos, and the apparently mandatory recitation of the phrase "this was the best convention ever!"
