Wow. It's a good thing PD didn't have time to finish the game the way it was originally intended or all the angry GT players in here would have had to find another game to play. Everyone seems to forget that when the game was announced, it was going to have cars, bikes, scooters, truck racing etc. I'm assuming it was just too massive of an undertaking to do it in time, but obviously PD didn't think it was silly or impossible to have bikes in GT. My guess is they could be added quite easily. Whether or not the different types of vehicles would race together is another story.
