The iPad edition … has been "completely redesigned" in order to be some 33 percent thinner while weighing 358 grams. The interior is refreshed, too, with a rigid casing that hides a slip-in cover and a built-in stand. Reportedly in response to popular demand, a black and a red version are joining the classic brown edition, with each one constructed from leather and offering up a dual zipper system.Twelve South has posted an extensive blog entry going over everything that's changed, including the new Classic Black color. BookBook for iPad is available for $79.99 from Twelve South's website and Apple Retail Stores.
Preview at WWDC likely in June, followed by September launch.
