Reading between the lines, I think GM is looking ahead to when they wind down GMC... They would then need a Denali equivalent at Chevy to go head to head w/ the Platinum, King Ranch, Longhorn, etc.
It seems very plausible to me that GM NA is moving towards having 3 very distinct brands w/o overlap..Chevy, Buick, Cadillac. GMC is redundant. It has been for decades.
This has crossed my mind too. If we see Chevy get more models and if GMC fails to get new things like the Granite etc. It may lead to that.
But with the new Granite pick up show truck just being shown I suspect GM is just doing this for the money.
This is just a simple easy move to make a already profitable vehicle even more profitable. I would never pay that much for a truck but if it makes GM a lot of money I am all for it.
I do not agree with this move on cars but on Chvy and GMC trucks the links have been tight for years. The average buyer for the most just think of them as trucks from GM anyway. Often the one they buy is the dealer closest to home and often that is a Chevy dealer. Heck GMC still offeres base models just as Chevy too.
Either way GM can get away with this in the truck line but I pray they do not go back to this in the car line.
