I can confirm that this Deluxe Edition Upgrade comes only with the art book and mp3 soundtrack. Unfortunately, the Description for this Deluxe Edition Upgrade contains 620 words that have zero to do with what this purchase includes. On the contrary, the Description only pertains to the base game (Extended Edition), which you must already own to purchase this upgrade. The base game's description is irrelevant to the purchase of the Deluxe Edition Upgrade. Only the Goodies section shows that it comes with the art book and mp3 soundtrack. Given that the Goodies section typically contains things that are included on top of (in addition to) the main purchase, it's easy to see how someone might be confused by the way this listing is presented, and it's far from what I would call "clear". The art book is a full color, 126 page PDF. It includes backer portraits and is nice if you're into that sort of thing. The soundtrack includes 22 tracks at 320kbps bit rate. These tracks are atmospheric, but for me personally, only a few of them rise to the level of something I might like to listen to outside the game. Overall, I'd recommend to pick this up on sale.
