No, they had a total of like 5 people working on it. Most likely they came out with a final beta version, gave it to their testers, then one of them exploited and made w/e the hell they wanted, and bam. Back to work for them. Seeing as so many people want to play this game I'm sure they wont take longer than 2004. You should see the Blizz WoW forums, they praise them when they release 1 or 2 screen shots.
