Challenger will get a refresh along with the new refresh Charger, the LX platform will finally be killed off and replaced by the LA platform. The hellcat Hemi will be a performance high end model. Time frame is the only thing that's screwy, 2014 we should see a refresh of the challe and charger followed by the all new cars on the LA platforms in 2015, with the barracuda/cuda SRT err a dodge at some point.
Not to mention the 2013 V10 concept Charger juice was out cruising around Fort street Michigan with Manufacture plates on it.
