Blizzard hopes action RPG Diablo III will launch this year, but when it comes to RTS StarCraft II: Heart of the Swarm, it's less enthusiastic.
"I don't know the answer to that," StarCraft II game director Dustin Browder told Eurogamer this evening when asked whether fans will play the game in 2011.
"We're working on it as hard as we can. We're really trying to push on this and get it out as soon as we can.
"I don't think you'll be playing it this year. That seems very unlikely to me. But we're pounding away on it as fast as we possibly can."
Activision Blizzard's financial projections are based on the belief that Blizzard will fail to release a game in 2011. The publishing behemoth guaranteed investors, however, that if this happens two Blizzard games will launch in 2012.
Heart of the Swarm delivers the zerg campaign – the second of three campaigns that make up the entire SCII experience. The first, Wings of Liberty, released in July to critical and commercial acclaim.
