So hey, this is pretty cool. I like to consider myself a connoisseur of video game art, owning a good number of hardcover, glossy-paged artbooks that help me out when a) I need some inspiration, or b) I need to feel really inferior about my art. The artbook released with the Collector's Edition of Wrath was very well put-together (and certainly an improvement over the original WoW artbook with its half-pages of pre-rendered art for every race but orcs and humans) and had everything I like in an artbook--but oh, what's this, Blizzard? An entire book that shows and discusses the process of making the Wrath cinematic? Yes, this will do.
Published by Insight Editions and titled The Cinematic Art of Wrath of the Lich King, it features 200 pieces of high-res concept art and CG renders, two 8x10 art cards with concept art of Arthas and Sindragosa the Frost Queen, lots of lore bits about major players in Wrath's storyline, and (I think this is the coolest) a 12-page illustrated storybook that tells the tale of Sindragosa. And even beyond all that, there's behind-the-scenes commentary about the cinematic every step of the way. It's valuable insight if you're interested in storyboarding, production, or just the Blizzard creative process.
I think we can all agree that it sounds pretty awesome, whether you're into art or WoW itself. You can pick it up, if you're so inclined, at Amazon.com for the very reasonable sale price of $19.77 USD. If you're as-yet-unconvinced, you can check out a preview of the book at Blizzard's Wrath site.
