I am awaiting my Christmas package from Laminar Research, but I have run the demo.The sky is incredible and a visual treat. The ground is a huge improvement. It adds a realistic wow factor for sure. I am not going to fuss about the logic of the roads or the moving vehicles on them. The point of this program is to fly aircraft, not chase down someones dodge pickup.The flight model is certainly differerent. Some of the aircraft in the program are better handling, some worse. I ported over a few of my own aircraft and again, some are a little nicer, another one is to put it mildly, a handful. so i have to do a bit more work tweaking them to be dialed in with 10,ATC and other aircraft are a lot better than before. unfortunately the other voices on the radio are generic monotonal robot voices. i would not be surprised if that is fixed in an update over the next few months.At this point, i am going to give it an entusiastic 2 thumbs up and keep checking my mailbox every 10 minutes.
