DS, from what the post says, August 2011, so if DE and the Inquisition are supposed to happen before then, they can still meet this deadline. Though, Dark Angels, not too sure if they want to do another SM army again so quickly. Maybe after next year and Dark Eldar, Inquisition/Grey Knights, Necrons, and then Tau they could do DA.
A tiny portion of humanity turned its back on mankind in the waning days of the last Golden Age. Over one and a half centuries later, the PHR has emerged from the shadows as an unrecognisable civilisation, its people irrevocably changed. They are no longer simple human beings, they are post-humans - cyborgs.
