Yes playable. If you was able to grab a hold of it, it's so awesome. If not,
Unlike MW, in carbon, kits, rims, all that nice stuff is fully sizeable and custom. Say you select a rim, you can change the size of the lip, how many spokes you want, the size of the spokes, if you want to spokes to go outward/inward, etc.. so much more.. same goes for kits and such; size of the scoops, shape, length, etc.. Graphics is top quality as MW, voices during races, scenary, roads, etc.. are very impressive too.
Oh, and on the demo, you can actually fall off the road and go over the rails and into the moutains..
very nice indeed. Many options for the actual release.
