UPDATE : September 8th, sudbury.com, posted an piece about Dodge's future moves. Dodge has said that they want to launch a convertible based on the new Giorgio chassis that could use the Barracuda name.
So it seems like that's pretty much it. I'm actually starting to feel like I want a hardtop version myself.
The platform will be used after 2018 and built in Italy, so it seems the 2019 goal may work out after all.
