That shot for the 2014 looks awesome! I love those mirrors, and split headlights will look cool, I'm definitely excited about the new body style.
Here is the AutoBlog article on it, showing new Interior.

You can also see a redesigned 3rd Brake light, and a possible bring back of the GMT800 style bubble tail lights.
Everyone is complaining about that interior. And I agree with them. I don't like most of it, but I highly doubt that is the final production dash. I'm guessing it's just a mule dash for the test vehicles.
