In addition to the all the above things mentioned, I would love to see the latest on the HMI/infotainment system they are going to come out with. I know they will be using Unreal Engine to help with the HMI layout, but I wonder if it will also make it easier to download/play Unreal Engine powered games as well. Even if that's not in the cards, it would be nice to show more of the infotainment. Some videos of GMC videos have shown off some of the widgets, but what is that Sasquatch looking one!? Google will be the base upon which the system is built so we can assume a great mapping system and voice recognition. Both Mercedes and BMW (I know not really competitors in most respects) have been showing more of their upcoming systems, so it would be nice to see what GMC are planning.
