Developer Infinity Ward releases changes and updates that are being made to Call of Duty: Modern Warfare 2 prior to its October 28th release. Presumably, Infinity Ward is paying close attention to Modern Warfare 2 players that had early access to the game and were able to play the game, test its performance, and share their thoughts. This is good news for players as, hopefully, it means that the game will run smoothly and be improved upon in various ways when it launches.
