Are you talking as in a refresh? If so, I personally don’t believe they will do a refresh, and will instead wait to see what Chevy does with the upcoming Camaro before making any moves.
Plus, Ford also runs a gt3 car now, as well as the Dark Horse in gt4, so a refresh may be a little weird if it looks completely different from the car they run in IMSA/WEC, but then again, they could always refresh that car with new panels, so who truly knows.
