They had been renovating the Check-in area between the B and C checkpoints for a while (the short-lived Midwest check-in area). Now I find out why. Before Delta, United, American, Continental, and Airtran were crammed in between the A and B checkpoints. Now United and Continental have jumped into the area between the B and C checkpoints and they are really emphasizing the Star Alliance affiliation.
I did not wander down to see if any changes have been made to jetBlue, Lufthansa, or US Airways.
