If that image is not an official rendering, then hopefully they are still tinkering with it and come up with something more exciting.
However, that image is definitely large enough to get an idea of what the building will look like. I wasn't the first one to notice that it looks like they're re-using old ideas.
I'm just crossing my fingers that the Calatrava and Studio Gang buildings can put Chicago back in the forefront of cutting edge architecture.
