Chris Metzen talks about the story and characters development for StarCraft II these past years, teases about a fourth race (more like he didn’t completely deny or closes the possibility down the road — coughs future episodes), but don’t hold your breath for Wings of Liberty.

Chris also talks about his work with voice actors and with Alex Afrasiabi building up content for several zones. Chris checks back with Alex about every two weeks to play the game and see how the development goes, and feels amazed of what he’s seen so far. I can’t but feel excited about Cataclysm. If the father of the Warcraft lore is amazed, that’s a thriller right there.
