The rulebook is still in the print proofs stage, as there's been a couple of problems with the proofing phase, but Newt expects these to be resolved soon and once he's happy with the print proofs will be issuing the codes for print copy backers of the Kickstarter.
However, writer John Ossoway was at the Furnace convention this past weekend in Sheffield, and Newt posted a pic of JohnO with copies of the print proofs of both the softcover and hardcover of the game.
Personally, the books look gorgeous and just whet my appetite even more for my copies of the River of Heaven book in hardcover! Bring it on, Newt! :)
