PacSim posted an update regarding their Salt Lake City scenery a few days ago (Friday, September 30). They are finishing up a few things like night lighting, taxiway signs, and others. All jetways will be animated, which is cool.
According to their facebook post, October will feature one last set of previews before release, so this scenery is nearing completion. I personally can’t wait to get my hands on it! You can see the preview images on their facebook page.
