I'll be a little more specific here since in this thread we can reference spoilers. In watching the totally revamped intro last night (I did replay it a couple of times afterward), it seemed to me that almost every clip (or just about all of them) are new; that is to say, even the clips of most of the world landmarks used before seem to be new material and not recycled from the SD-era intro. One for instance, is the Christ The Redeemer statute in Rio.
I recognize that some of the images were recycled (such as the one castle shot), but everything's been re-edited, and I got the impression that all of the Racer action clips are new. I am sad to see the retirement of that opening CGI passenger jet, I've always thought that was a cool image, and I hate to see it gone.
