ive seen my local store copy and its a slightly more extreme version of the marine book, with a bestiary and army list. though all the rules and wargear for each unit is described in the bestiary with just points costs and profiles listed in the main list.
also the book is too white for my tastes.
but ive very nearly become corrupted, with those brilliant new models and cool new weapons/rules... but my will is strong and i shall not turn from nurgles grasp
