IGN will be publishing NWN 2: Mysteries of Westgate videos throughout the week. See them here. The first one features a spectacular battle with much spellcasting taking place on a ship (so the adventure is not 100% urban, as some would expect), and there are more to come. Unfortunately, developers' posts in this topic indicate a small delay of the pack's release. Still, "it's coming soon".
