To take that thought above further, here's a thought off the top of my head...since Pontiac will be scaling down to a niche brand with only a few models, what if there were no Z28? What if the "top Camaro" was a WS6? That way Pontiac gets a halo car. Chevy already has the Corvette.
Now I'm going to hide behind this bunker before the bowtie guys start throwing things.
