Five(!) separate softback books, Indexes for ALL of the current armies. We will be able to play everything on day one. Damn nice. Of course the rulebook will be available as a stand alone item.
And that's not all! Command dice, Tactical Objective Cards, Wound tracker dice, and a set of objectives. Bank account prepare for impact!
Oh, and the basic version of the rules will be ready as a free download on the 17th. This all looks great. This should prove to be a good summer of 40K.
