Delta Green d20 finally surfaces

… insert Deep One joke here. At a price point of $35 in April. Hardbound? Doesn’t say. Given the supply problems with the CoC d20 core book, will this still do well (meaning, will it stand alone from the core book sufficiently to make it as a d20 worldbook)?
[UPDATE: I’ve received independent confirmation that the book will be hardcover, and will not only have d20 conversions, but some OGL content as well. – Allan]
