I was able to find some more information on this project.
According to site plans, there will be two hotels. A "Hotel Tower" which I assume is the Marriott hotel with an actual convention center building (for Live Oak) next to it. Then there is a 5-story hotel next to a Fitness Center. In between the two hotels is an office development. The southern portion of the development is where the retail center will be.
The red area is Gateway Plaza
