So a little more detail about the physics. Again, it is REALLY hard to tell anything in this type of environment (no sound and worn out T500RS), so take everything with a grain of salt.
The most distinctive car was the Pagani Huayra. IMO even the twitchiest cars in GT5 were pretty controllable. This thing was an animal. Way harder to drive than any car in GT5. This car had a very narrow slip angle where it was happy. Go beyond that and it is game over. Kind of reminded me of the Escudo, just in how it bites. Overall, I got the impression that the higher the power the more throttle control is required. You cannot just floor it, throw a little oppo and fly out of a corner.
Lower power cars FRS felt a lot like GT5. A little more natural feeling of understeer to oversteer and overall, more understeer than GT5 but otherwise the same. IMO closer to the real thing.
Focus ST felt great. Lift off oversteer and all. I have driven the real thing and this is a pretty good representation. I doubt they will model the horrible brakes that fade in 2 laps the real car has. Hopefully this is indicative other FWD cars.
I did not get a chance to drive the older cars, I will try to do that today.
Racecars are all about braking. They have tons of grip above 70mph. When the downforce kicks in, like in GTA, you can feel it. But the braking is an important point. Sure you can trail brake slide it in, but 9 times out of 10 this will result in over rotation. The cars do not like to be upset in any way. If you want to be consistent you need to brake in a straight line. You also need to pick your steering angle. Any mid corner correction really upsets the car. Overall, the super gripiness of race cars in GT5 seems to be gone. I am just happy the GTR GT3 actually turns in.
I do think the Pagani and race cars would be easier to control if I my CSW and my headphones on so I could actually feel what the heck I am doing.
Visually, the game looks great. Sunset/sunrise locals look fantastic. Shadows are a little softer but not terribly different from GT5. I only noticed hickups when I was racing the AI. Some frame rate drops like I said before and a little pop in. Not "horrible" but noticeable. Menus are easy to navigate and loading is quick. I think it is safe to say GT6 will launch in a better state than GT5.
Also, I am going to set up my DSLR again and see if I can get some high quality video. I will also bring my heaphones with an extension cord and see if they let me plug them into the TV.
