I don't know if you live in eu otherwise this might be interesting for you.

There's an additional 32 pages in the "Surviving As A Witcher" portion of the guide, an additional intro section entitled "Gwent: A Game of Cards" (goes over game basics and all cards), etc.
As for Main Game content, it seems to be exactly the same. What I meant by being more in depth (poor word choice really) was that it had more content and delved deeper into the game in regards to the DLC. Unfortunately, the entire art section from the C.E. release is gone.

""Amazon 3rd parties have them starting at $19 + $3.99 shipping." Is that the hardback edt.?" Yeah... here's the link: https://www.amazon.com/gp/offer-listing/0744017211/ref=tmm_other_meta_binding_new_olp_sr?ie=UTF8&condition=new&qid=1472796629&sr=8-1
