Ummm Blizzard? Why?

A Couple of days ago one of my friends told me about the new World of Warcraft Expansion "Cataclysm" where he then proceeeded to rant on about how the Lich King isnt even a killable Boss and they're releasing a new expansion ect...

Curious, i decided to see what it was about, arriving at the page, one of the first things i noticed was Deathwing's head. It is honestly quite similar to that of the Destroyer (add a second set of horns and put the horns facing behind the head instead of forward, and a nosehorn), however...

"Hidden away in a secluded sanctuary, the corrupted Dragon Aspect Deathwing has waited, recovering from the wounds of his last battle against Azeroth and biding his time until he can reforge the world in molten fire."

Yeah, Reforge the world, wasn't it the Destroyers role to bring about the dawn of a new world... by issuing its destruction?

Seriously Blizzard, i know as Activision-Blizzard you guys also now own the products of Sierra, but this is just to similar, to early.
