Privateer Press posted up a preview of a new character Dire Troll over on their website.
From the preview:
Outfitted with a crudely rigged bombard salvaged from a Khadoran Destroyer, Dozer is an impossible fusion of nature’s fury and mechanical destruction. From his perch atop Dozer, Smigg operates the wildly inaccurate bombard with surprising effectiveness and is revered as an ace by other pygs. So spectacular are their battlefield rampages that other blitzers are inspired by their example and strive to make every attack count.
