If you have not noticed CA for a the past weeks have been doing this "Ritual" event in thier website where if you answer the correct word for a riddle, you get an award. There has 3 of these Riddles so far, 2 of them were images of what is clearly Skaven imagry, and another is a Text Adventure game.
There are the 2 Concept Art for the Skaven:
As for the Text Adventure basically its about a High Elf or Dark Elf Scout that is exploring Ruins in the Lizardmen homeland of Lustria (South America) and essentially they found a Skaven Tunnel underneath it and the Elf Scout is killed by what is clearly a Skaven Gutter Runner.
But regardless, the Skaven are confirmed to be in Game 2. Soon the Filthy Vermin will rise from their holes to sweep across the world in a Vermintide!!!
