Since it's live, I thought I'd make a thread. These details are from GTPlanet.
Here's the full Spec 2.0 change list:
Major Changes and New Features
- Standard Cars now given simplified cockpit views
The over 800 standard cars included in the game are now given simplified cockpit views. You can change your view using the SELECT button when racing, to change your display to the exciting cockpit view.
*Unlike the cockpit view of premium cars, the simplified cockpit is shown in a dark silhouette, and the gauges used for the car will be standard in-game instruments.
- New Opening Movie
A new opening movie is now available from “Gran Turismo TV”. When you download this movie, it will replace the current opening movie. The previous version will be viewable within Gran Turismo TV.
- Addition of the weather change menu
On some tracks with weather changes, it is now possible for the user to set time and weather changes from the Quick Menu in both the Arcade Mode, and “Practice” of the GT Mode. Also, you can make more detailed time and weather changes while editing in the course maker and in the online lounge.
- Multiple car settings/save feature
We’ve added a setting sheet feature that allows you to save multiple car settings.
From the [Setting Sheet] on the lower right of the screen, you can check the current settings. You can switch between 3 settings A, B, and C, allowing you to change between your personal settings easily according to the type of race and your objectives.
