In case you weren't aware of this (like me), these awards go through multiple rounds of voting to narrow the field. Looks like Privateer Press got voted into the expansions category (for the Retribution Forces book) and the miniatures category (for epic Thagrosh and Wrongeye & Snapjaw).
Take a moment to vote at these links! You need to register with Tabletop Gaming News (free) if you haven't already. You have until the 22nd of December.
Go go Privateer Press!
