Darksiders 2 Argul's Tomb DLC Releases Early For One Gamer

I'm not exactly sure how, but a user has been able to gain access to the new DLC for Darksiders II a bit earlier than expected, in fact, he gained access to the DLC several days earlier than the initial reports stated. A slip-up by THQ or was it a PR error? Whoever is at fault, it's good news for one gamer.
