I looked at a picture of what is to be the new O'Hare proposed by Daley. The plan looks identical to what DFW is now. On two ends of the battery:
(-) This might be a desperation maneuver, no pun intended, to copy a proven airport layout like the one @ DFW which has far fewer congestion delays I think.
(+) If it is the case, it would work out very well for Chicago. I commute between ORD and DFW alot and it would be cool to see the planes take off and land over 294.
