Well, Im sadly believing we Wont Have Livery Editor, although, i still have Hope for Aerodynamic Modifications.
Also, Every car Will Have Cockpit, because I Know that Being a GT Series, they wont be That Cheesy of not Giving Interior to All Cars (Except Concepts, and Cars that never had one in Real Life).
About Damage, Only WRC, Nascar and Some Super GT Cars, but not Street Cars.
I dont Believe we will See Day/Night Cycle, but that we can Choose the Time of Day a la Live For Speed.
Im Expecting minimum 60 Tracks, the 20 thing Maybe was Gran Turismo Tracks, like from the 60 Tracks, 20 are Created by them...I Dont Know tho.
And Talking Bout Release Dates, i Think well Have it in December.
