When Starcraft II was announced on May 19, 2007 at the Blizzard Worldwide Invitationals in South Korea, fans were introduced with the notion that this sequel would focus on the differences and richness of each of the three races from the original game: Terran, Protoss, Zerg.

GameInformer interviewed Chris Sigaty [Starcraft II Lead Producer] if Blizzard planned originally to add a fourth race.  Sigaty answered what we already know.  Blizzard wanted to focus on the differences of the three original races. However, on this GameInformer interview Sigaty answered something that might be interpreted as a hint that a fourth race could be added in the Starcraft II Expansion Pack. Read the full interview.

GameInformer: Have you ever seriously entertained the idea of creating a new race?

Sigaty: We did. You know, we talked about that originally, but we felt like at least with the preliminary product, we didn’t want to sort of muddy it up and make it like one more race is the answer, that that makes it better and that’s it. The big thing about the original Starcraft is the differentiation between the races, and we thought that we could even further enhance that, there was more to add to the races. So rather than make it about another race, we wanted to play with extending those differences. Who knows what we’ll do down the line…
