I did some quick digging for site plans, will do more later. I only found this from a Trib article from last June.

I don't see a building that matches what Tom posted above. But these were all concepts, so who knows how it will all come together.
Also note: Somewhere in the background of that image, one of the parking lots, is where Lucian Lagrange's "Tenpenny Tower" proposal from last year will be.
