Kickstarter update #4 by Queen Games wrote:
--- Exclusive expansion
The art work of Expansion 1 Goblin’s Loot as shown in this Kickstarter will now be exclusive to this campaign and will be printed in a limited quantity. Most of this Kickstarter version of the expansion will be going to you, the Kickstarter backers. Any leftover Kickstarter versions of this expansion will be sold at conventions and used for promotion only. There will be retail version (expected to release sometime in 2016) which will have different art work on the cover, cards and goblin tiles however their functions will remain the same as the Kickstarter version.
So there should be a retail version somewhere in 2016. That's going to be a close call.
