OK. I now understand.
1. Kingdoms are now 40K Space Marine chapters.
2. Empires are now based on the movie Aliens. They have two kinds of hero units:
a. Alien Queen (Now called Alien Fallen Enchantress or AFE).
b. Face huggers. If they catch your hero unit your hero becomes an Alien (after a very messy graphic scene).
3. In a very unexpected move the next game in the Elemental series is announced as an expansion pack that adds Imperial Guard and Chaos.
