At very least it looks like the day/twilight/night cycles in the dealership are gone. That's really disappointing, it wasn't an essential feature, but I thought it was great seeing the different paint colours in the different shades of light before I bought a car. I'm going off youtube, I haven't got the game yet, but overall the menu system and the dealerships and car selection screens don't appear to be as pretty as they were in GT5. I'm thinking this has all lead to an improvement in loading times between screens.
