I'm glad they are doing as many races as possible, but the inclusion of fantasy china in the initial factions does not bode well for the game imo. Until now the base races were all actual races from the setting, not single paragraph throw away references. Meh.
It also means that stuff I was really looking forward to like the Ogre Kingdoms and Chaos Dwarfs which actually had army books will probably be DLC and possibly years into the future.
I think they will come earlier than u expect.
One of them will be the preorder race (they confirmed there is one), so it means it will be there at launch already. The other will be 100% the first dlc, so we will have both within 1 year after launch
