Proving that Deathwing wrecking up the joint can actually be a good thing, this recent press release from Blizzard shows us that after an initial burst of 3.3 million, Cataclysm went on to sell another 1.4 million copies over the next month.
This pretty much cements Cataclysm's position as a huge seller for Blizzard and brings this expansion up above Wrath of the Lich King, the previous best seller. It's unlikely that anyone is exactly surprised by this news, but it bodes well for the game and its current success.
