With only a mere few days to go until Blizzard opens the doors for their second expansion to popular RTS StarCraft 2, all eyes looking towards the third expansion. In a recent Ask Me Anything on Reddit, Game Director Dustin Browder has revealed that development for the third and final expansion titled Legacy of the Void is already underway with "Legacy story, scripts and missions" in-development.

Among the various question and answers on Heart of the Swarm specifics Browder also revealed that the team hopes for less time between the second and third expansion, saying that "efficient and quick game development is not something we have traditionally been great at," a nod at the coined term "when it's ready" that Blizzard are infamous for.

Browder was also asked whether there are more people working on Blizzard All-Stars then StarCraft 2, revealing that only a small portion of developers are actually doing so however "some artists who worked on Swarm now transition over to All-Stars while our campaign team starts work on Legacy of the Void."

Browder was also quizzed on whether the StarCraft franchise would consider moving to a free-to-play business model, which was answered with "We have not yet found design choices for StarCraft II that we would be happy with to make it free-to-play, so we aren't going to do it."

Alan Dabiri, lead software engineer also revealed that the team is hard at work ensuring the same ordeals that occurred to Diablo 3's launch issues (and also EA's SimCity) do not happen again. "We've learned a lot from our previous launches, including the Wings of Liberty launch, and we're doing everything we can to make sure this launch goes as smoothly as possible. We have the advantage that we've been building on an existing platform that's been evolving for several years."

StarCraft 2: Heart of the Swarm will be available on March 12th for PC. Many of the new features introduced in the second expansion will also be updated for the initial Terran-focused Wings of Liberty, free of charge.
