Many, many more units to come. Including "The smaller Titans and Stompas" No other game details yet other than it is a new hex based game engine. I really enjoy Panzer Corps, so I have faith this will be good. Even though Blood Angels currently cannot take Ironclad Dreadnoughts or Land Speeder Storms, it makes sense to me that they would have access to those units. More information as it is released.
