Adding onto that, GM stated they are going to keep their production down, and make sure dealer lots have fewer options to choose from. Which in turn will keep demand/pricing high (esp on these SUVs), rebates low/non-existent, and GMs profit margins thru the roof.
Personally, as a buyer, it makes things challenging. But looking at it from a business and wasted materials aspect, I agree with it. Generally speaking, customers will need to be more proactive when starting to seek out a new vehicle, and start looking 3-4 months out instead of just picking one off the lot like years past.
