I just got the game and I was hoping that they would fix the lag on the online version...I got to say that after playing the game for a couple hours I was impressed...although the online aspect is still pretty choppy!
I was the Emperor once which was pretty tight even though I was unable to kill any one.....
I also purchased BF2:Modern Combat which is also having issues with online play. I really don't know how they can fix it but the game would sure be more enjoyable if the lag wasn't so bad!
Oh well i will keep playing maybe it will get better with time! Peace out!
