For those who want to know more about the art in this book, Del Rey's Erich Schoeneweiss has additional information:
"Just off the top of my head I know we'll get our first look at "Callista Abeloth" in Warfare. I can tell you you'll see a fair number of new ships in Warfare as well. Ansel Hsiao, Ian Fullwood, Darren Tan, and John Van Fleet have all put real effort into designing and illustrating ships we haven't seen yet - Xim's warships, Tionnesse ships of various sizes, Hutt vessels (not the planet side skiffs and barges but space fairing ships), and the Wookiee Owool Interceptor. You'll also see the Anakin Solo (Jacen's personal Star Destroyer)."
The Essential Guide to Warfare will be released on May 22, 2012.
UPDATE: Del Rey has released 5 more photos from Star Wars: The Essential Guide to Warfare on the Star Wars Books Facebook page. We've already seen the first new image, as it is the cover art shown at the top of this post. The other four new images include a Tionesse Scout vessel by John Van Fleet, concept art of a Tionesse Raider by John Van Fleet, sketches of Hutt ships from the Yuuzhan Vong War era by Darren Tan, and concept sketches of the Wookiee Owool Interceptor by Darren Tan.
