VgChartz probably undertracked the game. There's no reason why Halo 4 would be the reason for the decline, remember last year MW3 competed with Battlefield 3, and that was on both platforms....
If these numbers are true then its a combination of Halo 4 + aging consoles +franchise fatigue.
Black Ops 2 did a lot of changes to the game....maybe the mainstream didn't like that? I know those Strike Force missions are hard as hell, even for me.I consider myself a pretty good gamer.
