GamesIndustry.biz quotes EA Mythic designer Josh Drescher says that Warhammer Online is being designed with longevity in mind, saying they have about five years worth of content:

"All the under-the-hood numbers all actually scale through the next five years," he said.

"What you don't want is when you launch the game you've got 40 levels - and it takes however long it takes to get to level 40. You then launch an expansion and it now takes two weeks to get to level 40 because now we need everyone to spend six months to get from level 40 to 50," Drescher added.
