I absolutely LOVED the first one for 360, even though I'm not much into racing games. If this game delivers, I'm gonna be so over it (for PC this time though).
The one thing in the trailer that puts me off are all the pictures of partying and whatnot, looks like they might have added some sort of "social" aspect with NPCs or something. I hope it's just for show, or to unlock clothing and whatnot, and not actually needed to racem or gain access to cars.
