Generic headline is generic because while the vast majority of pre-orders this week from Games Workshop are for The Horus Heresy, there's some Warhammer Underworlds and Blood Bowl in there as well, plus the latest issue of White Dwarf. If you're a GW player, you might just want to check it all out, just in case.
From the article:
The struggle for the fate of humanity enters a bloody new phase with fresh reinforcements for Warhammer: The Horus Heresy. Tanks, Dreadnoughts, Terminators, and the Liber Mechanicum, all on the same day? Excited? Well, just wait until you see the new Warhammer: Underworlds warband!
