How much will Heart of the Swarm cost?
We typically don’t provide details about pricing until the game is closer to release. We do view Heart of the Swarm as an expansion set, so for the regions that have a standard box business model such as North America and Europe, we will price accordingly. For other regions that have alternative business models, we’ll provide details at a later date.
When is Heart of the Swarm coming out?
It’s too early to talk about a specific release date at this point in time. As with all Blizzard games, our ultimate goal is to provide the best possible experience for our players, and we will take as much time as is needed to ensure that Heart of the Swarm meets the expectations of our players, as well as our own high standards.
