Pretty wild. When they announced Primaris this is what I thought they were going to do, but then after two full editions of old/new marines living together I'd assumed they'd given up on that idea. So many classics are heading out...
Wait, they're getting rid of Scouts entirely? That seems weird. Perhaps they'll get a replacement in the new reveals, but if not, that's a big departure.
@vladmech@OnlyAwfulNamesLeft that’s a popular rumor currently circulating. The GW article did mention most retiring units have analogues with Primaris, so new scouts does seem highly likely!
