As Microsoft announced, Forza Horizon 4 will get its first expansion pack on December 13.

As it was announced and promised, it will be "largest expansion' the series has seen to date, and features plenty of hazards in the shape of fierce storms and treacherous terrain, as well as the obligatory lineup of new vehicles and challenges".

Forza Horizon 4 was released on Xbox One and PC in October and it quickly grew in popularity. It already has more than two million players! I guess the number will become even greater now! It better happens!
