According to gamespot and most of the other review websites, the two new races will be the dark elves and the orks & gobbos. Unfortunately my computer never met the graphics requirement for the first one, so this is another one that I will be sitting out.
Warhammer Battle March is coming out for the Xbox 360, and will contain both Mark of Chaos AND Battle March, so I'm very excited, as I'm not a computer gamer. I wonder what races they'd add in future expansions... They already have; Empire Skaven Chaos High Elves Orcs and Goblins Dark Elves Dwarfs (Partial) Still to add; Ogre Kingdoms Vampire Counts Tomb Kings Lizardmen Wood Elves Brettonia Beasts of Chaos Daemons of Chaos Since they added Orcs, which were Dogs of war in MoC, and added another evil race, the natural progression seems to me to add the Dwarfs fully, and add another. My guess is they'll cheat out of doing never before seen ones like Lizzies and just go Vampire Counts or something. If they even do another one. Anyhow, your thoughts? A Lizzy vs. Brettonia campaign would be cool though.
