Modern Warfare 2, is heading to Modern Warfare 3, Infinity Ward's Mark Rubin has revealed via a series of tweets. Better still, Rubin says Terminal will be free for everyone, existing outside of the Elite subscription model.
Rubin says Terminal is in Microsoft certification now and the release date and official confirmation may not go public until Thursday or Friday. The map isn't confirmed to hit Xbox 360 first, but that is still an option. It may even drop as a title update, rather than a separate batch of DLC. MP1st has compiled a few of Rubin's tweets in one place, but he's still at it on his own feed.
