Wow. Are they going to do yearly updates, like the World Book? I’m actually expecting some sort of online (Hyperspace?) component/Databank revamp. Watch your back, Wookieepedia!
Whatever the case, Random House currently lists them as hardcover, with a release date as November 4, and the price at $75.
UPDATE: TFN has someone who got a few more details from Del Rey, namely that there will be ” full-color artwork.”
