Also on that website, they have a downloadable brochure for interested tenants. That brochure has another site plan that actually lists "Proposed tenants." I'd normally say these were just ideal tenants rather than real possibilities, except that some of the sites still show vacant. That says to me that the spots with actual names listed are probably at least spoken for, and quite possibly spoken for by the companies listed. They're fairly impressive but not so pie-in-the-sky as to be out of reach of the QC.
Here's a list of the stores on the above plan:
New to the area:
White House/Black Market
Banana Factory Outlet
Already exist in the QC:
Cold Water Creek
I was kind of hoping for a Cheesecake Factory, but this still isn't quite the "lifestyle center" that the QC is lacking compared to similarly-sized metro areas.
