There are leaked images out for this week's pre-orders from Games Workshop, including the cover for the new book Seraphon, the new repacks, and the broken down Tau Fortifications. Definitely worth checking out is the Forgeworld sections which include the Skatach Wraithknight, Corsair Jetbike upgrades, and Imperial Armour 11 .
