Robert Bowling, Infinity Ward’s director of communications and community manager, has confirmed that the studio has no plans to release a demo of Modern Warfare 2 prior to the game’s launch on November 10th. Posting on his Twitter, Bowling revealed that the team are far too busy adding the final spit and polish to the retail version of the hotly anticipated shooter to ship a demo before release.
“No plan for a Demo before launch. The entire team is focused on polish all the way up to ship of the full game.”
So, if you are still not convinced about getting the game and playing a bit more than normal title, your only hope is to watch all the trailers and read all the previews until a demo is available.
