Firebird version of the Camaro is pure speculation at this point. All pics of the 09 bird are chops of the Camaro concept. I don't believe GM will keep the same lines on both cars. I bet if they do a Bird version it will be more fluid and the Maro edgy. Similar to the way they did the Solstice and Sky.
By the way seen both yesterday and I have to say the Sky is one sexy machine. I'd take the sky over the Solstice any day.
