It's no surprise that Modern Warfare 3 will have its share of downloadable content in the near future, though it appears more content will release this time around than ever before.
Twenty pieces of downloadable content are said to release over a nine month period, as noted on ELITE's "What's Included" page, and this spans not only the multiplayer portion of Modern Warfare 3, but the "Spec Ops" mode as well.
ELITE members will get every piece of DLC for free, and will be able to keep them even when their subscription expires. Does that entice you to snag a year subscription?
