So far it would appear the illegal trouble is isolated to the Xbox 360 version of Modern Warfare 2. Microsoft has stepped up perma-bans.
Developer Infinity already announced they would be resetting the leaderboards and rank progressions to prevent unfair advantages when November 10th arrives. Microsoft has also stepped up its hunt for illegal copies played over Xbox Live.
Is it just a matter of release impatience, or is this a price rebellion?
