It's an odd feeling walking into Blizzard's studio to see new World of Warcraft content. The game has experienced such an insane degree of success it's easy to think it wouldn't matter if Blizzard charged 30 bucks (USD) for a new continent called Popcorn Festival Explosion Land populated entirely by non-violent plush kittens that randomly mrglmrgl like murlocs. It probably wouldn't be the best long-term business decision and would irreparably violate the consumer-developer bond of trust, but you've got to believe it'd still be gobbled up by the public.
