Infinity Ward will be releasing new content for Modern Warfare 2 but the kicker is that they will first release it on the Xbox 360 for one month, then PC and Playstation 3.
A Microsoft representative told Eurogamer, “We have a 30-day timed exclusive on the Modern Warfare content packs. So it will be available on other platforms, but you get to try and play on Xbox 360 first.”
We should be getting this around March and the first two map packs will included in this deal.
