Last June, research firm Intellisponse revealed that Turn 10 was working on Forza 3, a racing sim with over 400 cars and 100 tracks, new race modes, near limitless customization options, real world damage, online community features, powerful assist mode for new players, new cars and tracks as DLC. While Microsoft declined to comment on rumors, Kaarbo Design, the studio that also worked on the original Forza Motorsport, has now further validated the rumor by revealing it was working on Forza 3 and showed off a few race event sample posters stamped with the new title.
