Let me explain for you two:

In the 60s/70s the Camaro/Firebird shared the same body shape. So since the GTO is getting scraped, and Pontiac don't have a frame, the new Firebird might share the Camaro base, add a sprinkle of retrostyling and "Voila".
As every pontiac enthousiast, I'm waiting for a firebird revival. Contrary to the popular opinion, I don't like the new camaro, such project drawings generate some teeth grinding.
