With only three days before StarCraft 2: Heart of the Swarm invades store shelves worldwide, fans are eager to devour all the news pouring out from Blizzard as they build up anticipation for the second expansion. Today, however, StarCraft 2 Game Director Dustin Browder brought out some news regarding the third and final expansion, Legacy of the Void.

During a recent Reddit AMA, the Blizzard veteran was asked where the company would be a year from now in terms of developing the third expansion, to which Browder revealed they were already working on missions, storyline, and scripts.

This should come as no surprise to those who know how far Blizzard likes to work in advance, considering StarCraft 2 had playable builds in 2005. The team who completed Heart of the Swarm have already transitioned over to Legacy of the Void, save for a few artists who were sent to work on the upcoming Blizzard All Stars.

Given the recent online woes of both Diablo 3 and SimCity, some fans were concerned about Blizzard’s ability to keep servers running when each expansion is released – however, Blizzard’s own Alan Dabiri was on-hand to promise fans that they were adequately prepared:

“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.”

Legacy of the Void is planned to be the last title of the trilogy, and will feature a Protoss-centric campaign. As the aging race faces extinction, it will be up to Zeratul to save them from utter annihilation.

Of course, players will have to go through Heart of the Swarm first to see how these events are put into motion. While vengeance may be Kerrigan’s theme, it may end up as Zeratul’s ultimate achievement.

Given that almost 2 years came and went between the StarCraft 2:Wings of Liberty and StarCraft 2: Heart of the Swarm, players might be in for quite a wait before Legacy takes the reigns.

StarCraft 2: Heart of the Swarm will be released on March 12th, 2013 for PC and Mac.
