Fmulder points us to the Gamespot video of the Blizzard Merch panel from Thursday at the ComicCon. We’ve already posted screens of all the new Diablo 3 Merchandise, but you can hear a bit more details about the upcoming Diablo books.
Apparently there are Diablo books coming up as well as the Book of Cain; skip to about 11-13m for that discussion. It seems a safe bet that we’ll see more Diablo Novels, but no details have yet been released. We don’t know if Richard Knaak, author of the Diablo Sin War trilogy, will continue to be involved in the project.
