The one from the Collector's edition, will this ever be available to the public to buy? I just really want an artbook from the game and the "Book of Cain" just isn't what I'm looking for :/
Just use a primary auctioning site. You'll find loads of copies, but - as an answer of it - I don't believe you're missing out on much. I prefer The Book of Cain versus the Collector's Edition Art Book.
