The new 2015 Mustang is dazzling...WHEN WILL MOPAR ANSWER?!?!?

I've been a Ford guy since the 80's and have just recently got back into Mopars (hence the new Scamp). I drive a supercharged '12 GT daily, but I'm really getting tired of the same old thing. Do y'all think the planned major redesign for the Challenger in 2015 is going to be worth waiting for? The rumors all say shorter, narrower, much lighter, with improved versions of the Hemi. I could be a full blown "convert" if the new car ends up being a competitor. Otherwise, I may just pick up that Grand Cherokee SRT8 I've been watching.
