Those renderings are of the SOM design. Unfortunately, that is no longer the way in which the Lotte group is interested in going. I haven't seen any new renderings, but they've chosen another design team.
It's a shame because the diagrid option shown in the SOM renderings is amazing from both a structural and an architectural standpoint. The building would've tapered from a square at the base to a circle at the top. Maybe someone else will use that design.
