We are there now and it looks like the top will mimmick what the Contemporay now has with the California Grill. The thing at the top of the new tower does look like it could rotate.
I have heard that the thing on top will be a fireworks viewing area, they want to build it to keep people off the walkway that goes inbetween the A frame and that bldg.
Of course this is just rumor so take it for what it is worth.
