While the Forza Motorsport series is indeed popular, and is by many considered to be the best of the hardcore driving simulators on the market, it has in recent years been overshadowed in some ways by its less serious spin-off series, Forza Horizon. This more arcade-oriented, open-world take on the series, developed by Playground Games, is gaining traction with every new release, and since new chapters have been released steadily every two years, fans do expect a new Horizon game this fall.
And they just might get it. The game has officially been rated by the Brazilian Classification Rating Board, which deals with evaluating games for sale in Brazil. The rating was quickly removed, but someone managed to get a screenshot which you can find below.
The screenshot reveals that Microsoft Game Studios is publishing the game, and that it will release in 2018. As per usual with a portion of these ratings, the developer was not revealed.
