BlizzCon kicks off today with the opening ceremony, and rumors have swirled that Diablo 4 will finally be shown for the first time. Those rumors happened to start with a leak from the upcoming The Art of Diablo book. Releasing this Sunday during BlizzCon, The Art of Diablo takes fans on a journey through the history and evolution of the franchise. If you're itching to play the next Diablo, you'll probably have to wait a while. You can, however, bide the time by picking up The Art of Diablo for $31.50 at Amazon, which is $13.50 off the list price.

The Art of Diablo -- $31.50 ($45)
Published by Blizzard, The Art of Diablo has 250 pages of concept, design, and environmental art. There's an emphasis on new, never-before-seen art in the book, so longtime fans of the action-RPG definitely want to take notice.
Speaking of never-before-seen art, some of the concept art hails from the development of Diablo 4. Leaked pages from the book shows a return of Diablo 2 fan-favorite Lilith and other foes.
