I use the GM order guide quite a bit to see the differences between models and trims. Wanted to see if there were any plans to add Super Cruise to the Sierra AT4 for 2023 and noticed that the AT4X (4SG6) is not listed like it is for 2022. ZR2 Silverado is shown for both years. Any thoughts on why this is? I have found the guide to very accurate and up to date on what is and will be available.

When does GM typically launch next year's model year? At this point not expecting to see my 2022 Refresh until July so starting to wonder if 2023 will be out in August...
