Немного цитат Эрика (EricJ) с форума.
Про новую книгу: Yes, the main book is still required, this is 256 pages of NEW goodness, that adds to the world. There is an expanded Encounters chapter in there, which expands upon the chapter in the first book, but you certainly do need the first book to use this one.
Про то, что и где будет продаваться во время ГенКона (5-8 августа): Here is how it breaks down
At Gencon:
Everything shown! Boxes, blisters, Nightmare Dreamer, Miss Pack Promotion. Basically everything which you can see a image of, will be available, including the blisters which are released in future months. Of course, there will not be an unlimited amount of all these things at Gen Con, and we can only provide them as supplies last.
Online:
All boxes, Nightmare Dreamer, Miss Pack Promotion. The blisters will NOT be available online until the month they are released.
