"That is our goal, and sometimes it gets taken in a weird direction," he said. "Like you're failing [if] you're not releasing an expansion each year. It's probably going to be a long time before we get to the point where we are releasing an expansion each year."

Kaplan explained what the team would rather focus on:

"Our goal is to make an awesome experience, and obviously we felt that Lich King needed more time to get to where it needed to go," he said.

So while Blizzard is still aiming for annual expansions, "We're never going to slim down the content in order to make an annual date."
