Welcome, Lemhi. As they've said, all pricing info is speculation for now. FWIW, the July issue of Car & Driver predicts the price range for the Challenger to be $25,000 to $35,000. They're probably talking MSRP and pre-options. These guys talking $40K plus here are in it for the really hot Challengers. Me, I'll take a lukewarm $35,000 model.
Much has been said on this board about dealer markup over MSRP. For that, YMMV. Since finances require I wait 'til year 2 anyway, that doesn't mean as much to me.
As for colors, nobody knows yet. But its fun to speculate/wish!
