Oh yeh, so by the way, Steve has been hanging out at Blizzard for the last few days at a super-exclusive media event, checking out a little game that they've been working on called StarCraft 2: Heart of the Swarm. Now at long last we can finally reveal some information about this hugely anticipated title!

As noted in in the FAQ, StarCrafters can expect around 20 new missions in the Zerg-focused single player campaign, featuring Kerrigan as a playable hero.

Another change is the introduction of the Marketplace for custom maps, allowing map developers to charge for their creations:

Our ultimate hope is that the StarCraft Marketplace will function and thrive in a similar manner as mobile "app-stores" -- tons of free and premium content for players, and a limitless source of entertainment through StarCraft II and Battle.net.

Wings of Liberty will be required for Australians (although interestingly the FAQ notes that if you live in a region where you don't have boxed copies, that might not be the case - presumably something to do with the different retail model pursued in different territories, but not really relevant to us).

Our preview goes into a lot more detail about what you can expect - though beware, there are spoilers if you haven't yet finished the single player campaign of Wings of Liberty! We also have a stack of screenshots and concept art. You can watch the gameplay trailer here in HD or embedded below, and the Q&A contains a bunch of other information that is worth a read.

As you might expect, no release date has been announced just yet, so we'll all just have to wait until it is finished until we find out when we can get our hands on it!
