From the announcement:
This weekend sees another selection of miniatures for The Hobbit: An Unexpected Journey™ go up on pre-order on games-workshop.com. This time all of the miniatures come in our premium resin, Citadel Finecast.
The Gandalf™ the Grey & Bilbo Baggins™set features Gandalf™ the Grey with one hand on his sword, his staff gripped in the other; he is joined by the intrepid Hobbit, Bilbo Baggins™, who is vaulting over a trunk with Sting firmly clasped on one hand. Another characterful model includes the Gollum™ with Fish, which features him kneeling in a primitive boat with an expression of delighted awe upon his face, holding aloft a fish.
Other additions include the hammer-wielding Thrain, as well as the Captain of Erebor and Captain of Dale, both of which are excellent additions to last month's releases that included Warriors of Erebor and Warriors of Dale
