Forza Motorsport 4 will feature head-tracking support via Kinect, according to an MSN Autos report.
Kinect support was confirmed at E3 last year when the game wasn't even known as the fourth main title in the Turn 10 racing series, but not many details have appeared on the title since its announce at the VGAs.
"I think we're just scratching the surface," said Turn 10 director Dan Greenawalt. "I have the feeling that we'll all look back at these first few years of Kinect and reflect on it as a huge inflection point in interactive entertainment."
The report also said that T10 rented out race tracks in the game from two-to-three days to shoot "terabytes worth of video and photos, and tracing the inside, middle and outside portions of the road surface" with a commercial GPS system.
