Speaking to VG247, Forza 3 game director Dan Greenawalt has revealed that part of the studio is already working on its next game, but the identity of the title referred to as the "next big thing" remains a mystery.
"Right now a part of the team is focused on monthly DLC to support Forza Motorsport 3," stated Greenawalt. "Another core part of the team is off working on our next big thing, but we've got nothing to announce at this time."
So what could the studio's "next big thing" be? The obvious guess is Forza 4, but with Microsoft's other racing franchise, Project Gotham Racing, now sat dormant due to developer Bizarre moving to Activision, could a kudos revival be on the cards?
