Well after playing the new demo for an hour I can honestly say I won't be buying this game now.
Car handling just feels wrong and clunky. The online side suffers from people smashing you off the road to get past you, just like PGR3, the reason I stopped playing that online. The animation of the wheels looks pathetic, even though the car models look nice. From what I've seen on the demo the whole place look bland and boring. So you can drive all around it, big deal.
To sum up. Nice idea, poor execution IMO.
