Whether Pittsburghers or Clevelanders like to admit at, at least airport wise the situation is nearly indentical.

Pittsburgh is 39 with 7.5M pax
Cleveland is 40 with 7.3M pax
Some Pittsburghers thought the same logic (oh PHL is already too busy, blah, blah, PIT has so much room to expand) would mean that PIT would expand too after US/HP merged. Most of us knew better and the future has shown that airlines really only care about O&D, they don't care about how many more delays and cancelled flights you get from throwing more flights into congested airspace.
While the pull down may not be as dramatic in CLE, expecting an expansion means you should get your head examined
