Car models are looking awesome, as is the real time lighting (look at the lighting on the Elise near the fins). Looking really nice.
I just dunno whats up with Polyphony and their track design for their custom tracks. I think they can be alittle \'too real life\' which kinda makes them alittle \'too boring\' to look at.
One thing I am looking forward to though is real time weather and time of day, both of which will apparently make it into GT5. Pitty its still 2 years away.... Also, good to see they have Ferrari license, can only hope they get Lambo as well.
