At BlizzCon 2008, Blizzard's VP of Game Design Rob Pardo announced at the StarCraft II gameplay panel that the company would be breaking StarCraft II into three separate products. According to Pardo, the game's single-player campaign had gotten so large in the design phase that the company was faced with the choice of drastically scaling back the product or delaying it extensively. Instead of doing either, the company decided to break the product up into three different games, collectively called the StarCraft II trilogy.

The first game available will contain the Terran campaign, Wings of Liberty, along with a mini-campaign featuring the Protoss hero Zeratul. The second product will focus on Kerrigan and the Zerg and be called Heart of the Swarm. The final product is about the Protoss and is titled Legacy of the Void. Pardo was quick to reassure the crowd that this applied to single-player only and that the multiplayer portion would ship complete with all three races playable.


He also stated that gamers could think of the two subsequent products as expansion packs, but that Blizzard would be treating them as full-fledged games. No price point or release date for any of the products was announced.
