During a recent interview that Gamespot conducted with Battle.net project director Greg Canessa abou features such as broadcasting replays. Greg stated these features would be “a main area of focus we’re going to be seeing on the Starcraft  side over the next 18 months between now and Heart of the Swarm.”. This indicates that they are shooting for a release of the next installment of the Starcraft 2 plot in about 18 months.
As a Starcraft 2 fan I am definelty excited for more Starcraft 2 story. I may have fallen out of the Multiplayer just because I didn’t play daily like I should have. However I still loved the campaign and am itching for more missions as creative and interesting as the ones found in Starcraft 2.
