From the announcement:
Games Workshop's epic journey through Middle-earth continues with another wave of releases for The Hobbit: An Unexpected Journey. Available for Advance Order today are two new plastic kits and four models in our premium Citadel Finecast resin.
First up in plastic, the Grim Hammers are stout and sturdy Dwarf figures, and come appropriately equipped for defending the halls of Erebor. They're covered from beard to toe in heavy armour and wield pick hammers or sharp axes in a range of unique poses.
The plastic kits also include the Knights of Rivendell, which are an elite band of Elven warriors. These highly dynamic miniatures ride into battle sporting elegant armour and long lances - though the kit has options for one to carry a banner or a war horn, as well as casualties.
