NFS ProStreet - Hidden cars from EA!

EA has officially commented on the hidden cars in the game (McLaren F1, Aston Martin DBR9, Bugatti Veyron 16.4) , as stated on the official site: They will be available as a free download (FREE download). But many of us have already tried these cars... The only plus is that they will be tunable; before this, you couldn't even apply styling to all of them! EA also mentions two new tracks, Leipzig Test Track and Japan's Tokyo Expressway... I didn't notice them in the game, i.e. in the files of these tracks. A video with the "new" cars has also been released, you can watch it here.
I'm also posting a screenshot found on the official NFS site.
