We'll have the full details for you soon, but right now, we can tell you the Camaro Z/28 won't be called the Z28: it'll be the Camaro ZL1.
The info comes courtesy of a photo snapped during setup for the Chicago Auto Show by a member of Camaro5. The photo shows the Chevrolet booth display, and it reveals many of the details of the car in a triptych: the badge, the front end, and a wheel.
The shots reveal a unique front fascia, a high-domed hood with big vents on it, Wheels that dwarf the surely giant brake rotors inside (also wearing the ZL1 moniker), and the badge--apparently located on the side of the power dome hood.
