I hope they do this, I loved Forza Horizon, and judging by the image, I am interested in the setting and that the car there seems to be from the 40s. If this is true then I hope there is some focus on vintage cars because I was literally thinking about how much I would want such a game.
I also happen to know that the deep south is where NASCAR started by moonshine runners trying to evade police in modified cars like the one in the picture, maybe this will have a role in the game. I hope so, but I am probably digging too much.
