Yes, we have plans to update O'Hare with the new runways.
However, we don't have any estimate for a release date right now. It will be surely after the release of our next scenery (KLAS), which should be hopefully before the end of the 1st quarter 2009, but even then, we'll need to check if all the needed material, including aerial pictures and possibly airside pictures as well (in case there are specific buildings or other 3d objects in that area to add), to be available first.
