WTF! Since When did Books get Trailers?

From SlashDork : Doug Chiang's studio has released a trailer for his upcoming book. The book is a collaboration with Sci-Fi author Orson Scott Card of Ender's Game fame, and will include 75 pieces of Chiang's artwork. Chiang is the Concept Art Director at Industrial Light and Magic (and thus the concept art guy for the Star Wars prequels).

The Second teaser is very vivid and compelling. Also, is this the furture of book marketing?
