No new news-
I seem to recall reading somewhere here on the interwebs that they didn't want to proceed with this plan while the Marriott EDITION hotel was under construction on the North-West corner of 47th and 7th (701 7th Ave, or 20 Times Square). Traffic and congestion in that area will be dreadful until that hotel project is completed (allegedly later this year), adding the Palace Project to that would make 7th Avenue basically not passable, and with Broadway closed through Times Square, that North to South route needs to stay accessible. Again, I don't have a source to back this information up, as it was months ago when I read it.
I have mixed feelings on the Palace Rising. Part of me thinks that the engineers and designers they will bring in will do absolute top notch work and we will be getting a beautifully refurbished and patron friendly space. Part of me wants to see a full reno in its current footprint to protect against any risk that may be involved to the Landmark structures, Time will tell.
