Blizzard's Vice President of Game Design Rob Pardo wants us to think about Starcraft 2's
two followups, containing the Zerg and Protoss single player campaigns, as expansion packs, so does that mean they won't contain as much gameplay as the Terran-based initial game? Plus, you'll have to wait at least whole year between "expansions." Said Pardo, "With any luck, it would be like a year for each successive one, but that's going to be a target date, that's not a promise."
won't be out until 2009, you won't be able to play the Protoss single player until at least 2011. That's a long time to wait. Check out what Rob said after the break, and start yer speculatin'.
