Cataclysm Trademark by Blizzard Entertainment

According to the dictionary, Cataclysm means "an extensive flood or deluge."

Blizzard Entertainment of Starcraft and WOW fame has recently trademarked "CATACLYSM."
Now the rumors are starting to fly around for the reason behind this.

But all evidence points to the fact that Cataclysm will be used by Blizzard Entertainment for the World of Warcraft expansion.

Fact you might wanna know: The Sundering which created the maelstrom in Warcraft lore is also referred to as the Cataclysm. There's now a possibility that Blizzcon will be unleashing a sea-based WOW to all the WOW players. Exciting!
