Rumor: WoW Cataclysm pegged for early 2011 per retail listing

Blizzard hasn't dated its World of Warcraft expansion Cataclysm yet, but retailer Amazon seems to think it will be released in January.

According to several tips from Kotaku readers, folks who pre-ordered the Collector's Edition of the game from Amazon are receiving emails stating the estimated delivery date of the game will be as soon as January 4, 2011 or as late as January 18.

Here's a sample of one of the emails below:

Hello from Amazon.com.

We now have delivery date(s) for the order you placed on August 17 2010 (Order# xxx-xxxxxxx-xxxxxxx):

"World of Warcraft: Cataclysm Collector's Edition"
Estimated arrival date: January 05 2011

The date itself is not listed on the Amazon website, but retail superstore Target has it listed for release on December 31, 2010.

We'll mail Blizzard and see what it has to say on the matter, but we dont' expect any information other than a possible "wait until BlizzCon next month".

BlizzCon takes place at the Anaheim Convention Center in Anaheim, California October 22 and 23.
