Well, I just got back from picking it up, and let me tell you, I'm tickled pink. The Nappa Leather interior (which includes the dash), is really nice, and the Adaptive Drive rocks! Just from the little bit of driving I did on the way home, I can tell that the body roll/lean is all but eliminated.
One thing I didn't know is that the rails in the back have been eliminated. There are still four tie down eyelets, but the rail system is gone. While I never used it in the two years I had my 2010, I always thought about getting the attachments for securing cargo (I use my X5 to haul photo gear in connection with my photography business). More cost savings, I guess.
Here's some pics, including the old and new, side by side:
