User blog:Era of Anarchy/New MW2 Map Packs

I am wondering how many map packs they are releasing and the COD4 maps that'll be returning. I also want to know if they are releasing any more Spec Ops missions, Perks, Challenges, Kill Streak Rewards, Guns, Equipment, Melee Weapons, Titles, and Emblems? Please provide a source for clarification purposes, because I do not believe everything I read on the internet. Thank you!
