2013 Shelby GT500: where will it be shown next outside?

I tried to take picture at the Petersen Museum Deuce Week
but it was parked in dimly lit area.
Maybe it will be at the Amelia Island concours?
Question: Is the front lower spoiler a lot different than
that on Shelbys before? I read about the big increase in downforce. From a distance I can't see that much additional aero tuning. And those vertical blades on the rear undertray(there's a technical term which I forget) , I can't see
they do much good unless the bottom of the car has gutter leading to them like the Ford GT of '05-'06.
