Per this post from Ford CEO, seems the trend will continue with special editions. See LinkedIn post attached. Not that this is surprising news, but good to hear that the current model seems to only be refined and interior options are being considered.
For refence traded in a 4dr Heritage with sig lights, slide out tailgate and 20k miles and received 44k for the trade in. Initially they offered me 38k. Don't take the first offer would be my advice. They currently have my previous 4dr listed at $49,900
