I have no idea what people are talking about. I have significantly fewer lag issues on this game than I ever did with MW2 (I never got Black Ops). If I play for about 3-4 hours, I'll probably have one match with mild lag issues for a small portion of the match and like 1 match where I'm booted back to the main screen because of lag. Other than that, with the exception of the people who cause lag on purpose (I report those assholes) I have no issues. And really I only see people causing it to lag every 4 or 5 times I get online to play.
