Hey, don't be mean! I am very sensitive about my turkey legs.
Anyways, Blizzard has not given a concrete release date, but here is how I see it. They want to release a game a year for the next few years since they have so much in production. With Cataclysm coming out at the end of this year, I see Diablo 3 coming out sometime next year, maybe around September of 2011. StarCraft 2: Heart of the Swarm will then come out in 2012. Then the next WoW expansion in 2013, followed by StarCraft 2: Legacy of the Void later that year. The new IP they are working on will come out sometime after that in 2014.
Really, these are just guesses, but I am very confident this is going to be the order of releases for the next few years. Blizzard can easily extend out any of these games though, so I would just wait till they give a concrete announcement.
