I'm confused by that, you mean that in split-screen and career it'll have 12 cars but in online races, there is up to 16 cars? Why would they cap the number of cars in career mode then?
I asked the cutie at the booth if the game would allow more cars this time, she told me when you play single player it will be a maximum of 12 cars, but if you play online multiplater then it would be a max of 16 cars. Subject to change I suppose but that's what she said. The guy that was playing the game in one of those funky sitdown cockpits had 12 cars in his game. The game looked really good though and was buttery smooth even with lots of cars on screen. The had kinect head tracking working which was cool, although there was a bit of lag on it.
