The leaked images are out, and there are a lot all in one big swoop. Which means I have not read all of it yet. A new Space Marine Codex Supplement that holds a lot of rules for the various Space Marine chapters, White Scars, Raven Guard, Iron Hands, Salamanders, Imperial Fists, and their successor chapters. In only 128pages its going to be an interesting book, updating rules from various locations into a single book.
