Nothing confirmed. Torsen has been quoted as "available" in press release, as well as supercrew vs extended cab.
I don't believe there has been an official press release on the tailgate, but there are pictures both ways, and there has been verbal confirmation from reps that it'll be an option.
Will likely be some sort of tech package with cameras, nav, etc. e.g. 401a vs 400. Same thing like graphics pack like you mentioned.
What I really want to know is what stuff will be lumped together and what stuff will be a la carte.
