User blog comment:AdvancedRookie/Activision hints at more frequent DLC and content variety/@comment-1854594-20120106082358

Anything that doesn't require me to download a huge patch to play online like the one for Battlefield is good for me. I have no hard drive space left at all, and I only have dlcs for games I either A. Play all the time, or B. If I delete the dlc my saves will corrupt and be unplayable on the games they are for (Such as Fallout)

So if they do that, until I can get a bigger hard drive, I'm stuck online MW3-less.
