User blog comment:Damac1214/Sales of Black Ops II are a "Cause of Concern" for Activision/@comment-108.82.95.145-20121202211308

Heres the reason why BO2 sales decreased:

1) Because of the shittyness of MW3, many people lost faith in the CoD series and played sum game else.

2) Halo 4 was released 1 week before BO2's release.

Even though I see about 350K people online for Xbox, it doesnt concern me and it's the best game ever made, and i also consider BO2 as an apology for MW3, and i proudly accept it. :)
