But the Legion and Grand Legion are from the Glotkin and Thankquol end times books. Aren't CA sticking to the 8th army edition? May be they will add in some end times, they do seem to have hinted about the Chaos menace, so who knows?
If you are correct, that's just not plain good enough. Your front end PR person should know quite alot, otherwise it's embarrassing and unprofessional. I wonder if he ran off to find the answers the first chance he got?
