This article suggest there will never be a Firebird again, but probably a GTO.

........Thank (or blame) Bob Lutz, GM’s deified product guru, for that. He has asserted that the days of product sharing and badge engineering are more or less over and has stated emphatically that no carbon copy of the Camaro will make it into any other GM-brand showroom. The challenge, Hopson said, becomes making a new muscle car unique enough to appease Lutz and the market at large without being too unique for those Bud-guzzlin’, mullet-draped traditionalists who see it as their mission in life to ensure any future screaming chicken returns as “Pontiac’s Camaro.”
I apologize if you do not have a mullet style haircut and you do not consume alcohol as this article suggests that you might.
