Having sold 3.3 million copies a World a Warcraft: Cataclysm on the first day, it be easy t' guess that the MMO expansion would have little trouble going on t' record-breaking sales in it be first month on the market. 'n that be exactly what it be done, according t' Activision Blizzard, who reports that the title sold through over 4.7 million copies since it be December 7 release. 'n unlike the usual retail sales numbers, that includes both packaged copies 'n digital distribution.

According t' Activision, that sets a new record for monthly PC sales -- again, it be not a vast surprise t' believe WoW has the power t' break sales records. Here's what be surprising, though: Activision said that the WoW community be currently over 12 million players strong. Who be the 7-plus million people who play WoW, but didn't buy Cataclysm yet?
