Probably.
Blizzard will not release the second game in the StarCraft II trilogy, Heat of the Swarm, until after 2011 probably.
That’s according to lead producer Chris Sigaty, who offered the titbit during a story question and answer panel at BlizzCon, reported by IGN,
Sigaty’s comments tally with those of Battle.net project director Greg Canessa, who hinted earlier this month that Heart of the Swarm was scheduled for release in early 2012.
