Apparently after the success from the BO1 and BO2 ports, IW is thinking of making OG matchmaking, which is great. Honestly we need to be vocal about concerns for MW4 because it has a lot of potential, Personally I think the movement is to fast, so we should give feedback, Tdawgsmitty interviewed the IW devs and they said that they are looking online for feedback, so hopefully we can convince them to make the game a bit more classic.
