User blog comment:Damac1214/Sales of Black Ops II are a "Cause of Concern" for Activision/@comment-4160204-20121201205642

Well, MW3 left a bad taste in the mouths of several consumers, and those who are experiencing terrible connection issues (myself included, host is a death sentence) with Black Ops II have been further disappointed with Activision's flagship, so it kinda makes sense that there has been a drop in sales.
