Except that is just an order, with no timescale. Say that's over the next 2 years, maybe 3? I can fully believe that, based on the amount of time Blood Angels spent with a WD codex. GW still won't have a fixed release date for anything but the next codex. They will have a rough idea of what they are going to release over the next three years, for all three systems, but have always been very flexible with their time scales because of the creative nature of their work. They don't like to publicise a release date until everything is ready to ship (bar mass producing Finecast items and some plastic sprues, for stock management/storage reasons, mostly financial) because when they have in the past, and then something has gotten delayed they have had masses of complaints.
