Sumeet Surve, an artist at an Indian production house called Dhurva Interactive, shared two images titled "Forza Deep South," each featuring vehicles speeding through what appears to be the American Bayou in Louisiana. It's unclear if Deep South is simply the title of the pieces, or the subtitle for a new Forza game.
Forza Horizon was developed by Playground Studios, a UK team that set its open world racing game in Colorado. A sequel in the American South is plausible. On LinkedIn, numerous Playground team members claim to be "Currently working on an exciting unannounced title for Xbox One."
Artist Simon Gibson says he's "Responsible for overseeing the internal and external (outsource) production of all vehicles for for the project." It's not an outright connection to Dhruva Interactive, but it's a logical, possible link.
