Here's some recent shots of the 2010 Camaro, notice how the big round "retro" 1969 Camaro type headlights of the concept car are not present but instead much smaller headlights:

Also notice how the rest of the car is pretty close to the concept. Damen per a conversation we had last year, looks like the dual exhaust borders of the concept car are gone, it has a more conservative lower rear bumper cutouts.
