There has been no words about new models.
-The Avenger is going away next year. There is a replacement for its Chrysler 200 cousin, but nothing so far for Dodge.
-Chrysler/Fiat has already announced there will be only one version of their next Minivan. Which will almost certainly go to Chrysler.
-It has already lost all its truck line to the new Ram Truck brand.
-The new Viper is sold under the new SRT brand, it's not a Dodge anymore.
-Yes, there is a new redesigned Challenger coming soon. But it will probably also be sold under the SRT brand, as a Barracuda.
Put all these news together and you have no future for the Dodge brand.
I think Fiat made the decision years ago. They're just not ready to announce it yet.
