According to the Major League Gaming organization, the World of Warcraft tournament planned for MLG Dallas, which includes the season’s championship, has now been postponed due to Cataclysm.

The following release was provided by MLG:

 

Due to technical complications related to the upcoming World of Warcraft: Cataclysm expansion pack, the 2010 MLG Pro Circuit World of Warcraft National Championships will have to be postponed. This means that there will be no WoW Finals Event on site at MLG Dallas, and subsequently no WoW live stream. However, MLG will still hold a 2010 National Championships for WoW at a later date, and more details about that Event will be released in a follow-up announcement.

We sincerely apologize for the necessary delay in holding this highly anticipated event. The technical complications are a byproduct of the WoW Arena needing to be disabled temporarily prior to Cataclysm’s launch, the period of which happens to align with MLG Dallas’ dates. We are working with Blizzard to get a full understanding of when the Arena will be up and running in the necessary capacity to complete our 2010 World of Warcraft Season.

Blizzard has been and continues to be an incredible partner to MLG, and we understand that the development cycle and release of a game as massive as WoW: Cataclysm can’t always take our needs into account. We thank you for your understanding, and look forward to bringing you further news about the rescheduled 2010 World of Warcraft National Championships.
