Early on in the life cycle of WH2 there was regular speculation that the Dogs of War (or Southern Realms, however you prefer to call it) would be a playable race in WH2. It made sense; there were all these foreign colonies of the Old World located in the New World, many of them had been settled by Southern Realms countries, and the DoW in general were known as explorers and adventurers.
However, this has so far not come to pass. Mechanics people once speculated might go to the DoW, such as a horde faction that serves a settled faction, or paid contracts, have gone to New World characters like Alith Anar or Nakai. New World settlements that might go to the DoW have become minor feeder settlements to major factions like Hexoatl, or have been occuptied by other LL factions. The general theme of New World exploration and conquest has been seized by existing Old World races, with characters like Markus Wulfhart or Repanse de Lyonesse.
Are the DoW/SR still coming? If so when? And with all these developments, will they still take the form we expected?
