Been playing the demo for quite a while now. I would say EA improved a lot for this NFS. Especially for the traffic physics. In all pervious series of NFS, when you try to get the best racing line and if you are unfortunate enough to have any traffic in your way, you will be screwed for sure since the traffics are like gaint moving rocks. But in NFS:MW you can push the traffics away and your car will slow down instead of hitting a gaint moving rock and stop dead. The other great thing would be the pursuit mode. It is a lot better compare with NFS:HP2. In addition, the weather effect is quite impressive. When it started the rain, the environment will become cloudy and dark, there are more great improve I cannot list in here. Overall, I think NFS:MW is one of the best series if you like destroying police cars. (you can't do that in real life and don't do it in real life :P but it is fun, believe me)
