okay well there are really quite a few bad "previews" in that thread. At least more than good ones though naysayers are usually louder 
summarized some points:
- bad presentation
- some screentearing (probably not that big of a deal)
- bad menu music, bad engine sound and bad collision sound
- apparently Dirt 2 cars look better (though keep in mind that it's still a German site, could be PS3 OR PC version)
- bad looking landscapes, the trees aren't even the worst. Bad shadows (one poster also mentions bad lighting and bad smoke effects)
- collision damage only available Level 20 and up
- unrealistic bouncing off the walls
- some say rubberband AI, some say not
