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."

Since SC2 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'.

With the announcement about Starcraft 2 being a trilogy, do we know how long it'll be between releases?

We don't know yet, because we don't even know when the first game is getting released yet. I think there's some feeling out there that because we're treating each of the campaigns as almost like separate products, that people have somehow confused that into they're going to be separate products. In a lot of ways, you should think about the follow-ups as being kind of expansion sets to the original. It's just that the campaigns are not going to feel like expansions, they're going to feel like full, independent stories.

So, you know 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.

Do you know what the pricing on it will be? People are bristling at the thought of having to pay for a game three times.

We would do the retail price based on the value that we're putting in the box. So, if the value in the box is less than the original, then we're going to price it like that. We're not just trying to get people to pay full price for something that's less, if the followups end up having the feature set of an expansion, then that's how they'll get priced.
