User blog comment:AdvancedRookie/Activision hints at more frequent DLC and content variety/@comment-75.53.203.231-20120106024624/@comment-1854594-20120106083145

In other words, whether you buy the dlc or not you have to download it to still play online? Why do they assume everyone has several gigabytes of hard drive space free at all times? Because I don't. If they put out even almost the size of a gigabyte patch I'd be screwed. My 20GB hard drive is full. I'd have to get rid of the Black Ops map packs, which would mean getting rid of the zombie maps, which I play alot!
