Today's Games Workshop Digital release is a Battlescroll, Warhammer Fantasy's equivalent to the Dataslate. This one gives Vampire Counts a new formation that consists of 1-4 unts of Skeletons, 1-2 units of Grave Guard, and 1-2 units of Black Knights, and 1 Wight King.
It appears that there are several more formations in line for Fantasy this month, following the line up of Holiday Bundles out there. Here is a direct link to the bundle for the Restless Dead.

The remaining Holiday Bundles the following, and I expect that these are up soon for formation rules from Games Workshop Digital:
Creatures of the Chaos Wastes
Crypt Scavengers
Warhost of Naggaroth
