Great find, Melissa!
It looks like GM is going in the right direction with the Camaro, I think offering a V6 model is important for sales, therefor is a necessity. (Look at the bazillion V6 Mustangs running around.)
The two mistakes I think are
1) Independent rear suspension. I think most Camaro owners have thoughts (or intentions) of drag strip racing, and we all know how great the GTO's IRS is at the track.
They should have kept the solid rear axle.
2) Late 2008?! by then this car would have been hyped for what, 2 years? I think some people might not want to wait that long. It's like holding a great toy in a kid's face, but not letting him grab it. Eventually he's gonna go find another toy.
Don't get me wrong, I want to see GM succeed here, and have another great muscle car on the streets and on the strips, I just hope they learned something from the GTO marketing failure. You can't just have a great car, you have to be able to market it well, also.
