Wouldn't be surprised if JC Penney chooses to leave QSM, and instead chooses to locate a new store in Chisolm Creek. Similar to what they did when they left Crossroads to move to Moore.

As has been said, QSM is lucky not to have a lifestyle center to compete with. I really think that had the Tuscana development (towards the north of the mall) become a reality, QSM would've been a goner.

And the demographics around QSM are more varied than you'd think. There are some nice neighborhoods close by, but there are also a lot of run down 70's and 80's apartment complexes, like the 122nd and Penn area for instance. What keeps Penn Square going is the concentrated dense wealth in the Nichols Hills area. With Quail, the wealth is so spread out, and even then, it's just as easy to jump on the Parkway and head down to the nicer mall (Penn) than it is to drive across town to go to Quail.
