Not sure what I was proved wrong about on the tracks, but I've said that I was ecstatic with the return of Nurburgring (not sure if I have on here), and the general fact that they've given us some free tracks (Long Beach, and either Road Atlanta or Road America, can't recall).
Thing is, great as those gifts are, that doesn't make the cars worth $50. I wouldn't want to pay $50 for 3-4 tracks and 60 cars. I mean, you talk about the man-hours in the free tracks, but it's not like they didn't put those into the original 13 tracks. So, even if the tracks were in the DLC, you'd be talking 4 tracks and 60 cars for $50 vs. a full game, 200 cars, and 13 tracks for $60.
