Theres a demo in this month OXBUK. Its a single course that takes about 4 minutes 30sec and gives you a taste of all road surfaces, mud, and gravel and tarmac only one car Peugeot 206 WRC. The structure of the game is eerily similar to 2004 in all respects. You do simple challenges to gain better equipment and the modes are the same as 2004 except they are much larger in scope. Graphically its an improvement over 2004, there lots of depth of field effects going on and the damage model is very well implemented, although the car takes hell of battering before you notice its affecting the cars speed or handling. As for the handling again it seems very similar to 2004 although maybe the cars seem slightly lighter. All in all it seems very playable but I can't see a big difference from 2004 in fact the biggest difference is its fully Live compatible.
