New cuda ?

Can someone clarify for me why we need a "New 'cuda"? What's the purpose? We've got Challenger, and Charger.

There's no effort by GM to produce a retro Firebird to compete with their own Camaro, and Ford doesn't seem to be in search of another Cougar to add competition to it's own Mustang. Why would Chrysler need something to compete with Challenger?

I'm not sure I understand the business logic in play here. Not being a wise ***, just asking a question.
