New Black Legion will be in a boxed set with new Space Wolves, new Abbadon model and Chaos Chosen, plus a new Wolves character and some other stuff. End of year for the boxed set.

Angron and new Khorne will be coming too, although may be next year now. Angron is gonna be huge

Also here's a big one: Kroot Codex. Hard to believe, but the source on this has never been wrong for me.

Russ is returning - old man Russ, looks a bit like Odin - and he will POSSIBLY have 2 forms like Morathi

A Kroot Codex? I tend to find that one hard to believe, but possibly....These a rumors, and one that a lot of salt should be used.A source of mine has just let some new rumors slide. Heavy salt, but he predicted the Nurgle demons release a month before it was announced, along with knowing about the Death Guard/Primaris starter early and knowing about the new Knight back in November, so... I'm trusting him on this one. Your millage may vary, of course.
