I was really hoping that observation deck was going to stay. But, the building still looks WAY better overall. Here's a comparison of the original rendering versus the current one. It looks like many things were removed from the scope including the dome on the entry, the arched windows under the planet hollywood sign, and the base to the tower (as well as the main tower itself).
If that white structure in the back to the left is the outdoor dining terrace, it looks like it may have stayed, though!
