Toys N Bricks forum members have found this shot of LEGO Star Wars set #8129, AT-AT Walker.
Retailing around $129-$149 USD it will come with seven minifigures: Luke Skywalker (pilot), Han Solo, C3PO, Hoth Rebel Trooper, 2 Snowtroopers, and Imperial Officer.
We can't tell much from this shot, but all of these figures have been available previously and recently. If you are a fan of the new AT-AT design, then it may be of interest. If you are looking for a good buy on figures, then you might want to pass this one up.
More details as they become available...
