The next Forza game is set in an open world. Wait, what? Yes, it's an open world modeled after Colorado. And smack in the middle of the game's setting is a racing festival that you will partake in when Forza Horizon releases October 23 for Xbox 360.

Forza Motorsport 4 will debut fall 2011, bringing the power of Kinect to the increasingly popular racing franchise. The first trailer's mostly Top Gear USA footage, but the screens give a hint of the new look for the sequel.
