Future expansions.

Goblins are not beastmen; they are creatures bred through experiments on goblins.

What's your point? :confused:

In any case, if the DLC comes out before the expansion, the faction from the DLC will still be included in the expansion :)!

And, frankly, I can't imagine how you could introduce a faction without a campaign for it and multiplayer maps with a new type of terrain :(.
