No adaptive cruise, no magnetorheliological suspension, and a face that looks like a Star Wars Storm Trooper in white. I had the first two in a GMC Denali and grew to like those features. No reason Chevy can't do the same. I'll bet it's some kind of corporate decision. I'd like to hear Bob Lutz expound on this.
Other than that, the 10-speed and less weight would be nice but not enough to tempt me away from my current ride.
