Every two or three years, one car magazine or another trots out a "complete redesign in ThisYear+3" article. If they don't have actual news, they speculate. It's the only way to fill pages in an industry that doesn't have actual news very often.
Some day it'll happen. But in the 13 years I've been driving a Charger, it hasn't happened yet. I wouldn't bet money on it either way, and I won't invest any emotion or cogitation in it.
