The official plans for gate reallocation are coming to light now.....

Basically, in summary:
United to gain six gates.
American to lose four gates.
Delta is losing three in Terminal 5, but those are getting picked up by Southwest, which will not have three dedicated gates.
Air Canada / Alaska each lose a gate.
It remains to be seen where exactly these six new gates will be, and if UA will finally start to creep into Terminal 3.
Either way - AA has their work cut out over the next year to ensure they don't lose additional gates in the future. Also appears we are getting closer to the new satellite actually breaking ground. Several bids have been hitting the streets on the ORD page for the actual construction of the new concourse.
