Shortly after the release of GT5, it was no surprise to see that Microsoft took the opportunity to announce Forza Motorsport 4 at the VGA yesterday. Not much to see though, except for this short trailer containing live footage only but we can assume Turn 10 will include dirt, snowy and wet tracks this time. Maybe even snakes and cows! We've also added the packshot of the game, nothing too flashy as you will see. Update: Four images added.
