There are three DLC packs for the game: Teeth of Naros, Legend of Dead Kel, and a Weapons and Armor pack. The Weapons and Armor pack are not available on Amazon's DVG store and thus was not included in the $12 deal. It's not that big of a deal as a DLC pack compared to the other two. I was just curious if Tony knew if it would be added to their offerings in the future. If it's not then no biggie given that the studio is dead and how it's just icing on the cake.
Thankfully, everyone in this thread seems to agree that it's no big deal not to have it, and that $12 for the base game and other two expansions is one hell of a sweet deal already.
Ah, I see. I seem to recall that the other two expansions have a lot more content than the weapon&armor pack as well, and were also more expensive.
