Just wanted to chime in here. Again I've heard more talk of Berzerkers riding Juggernauts, and the new models will be interchangeable with Fantasy! So Chaos players that follow Khorne can either have Brazen Knights in 40K or Fantasy.
OH, and this project (Legions) was slow going start shortly after the release of the current Codex...but when it came to my ears a few years back, it was Phil working on it.
