The first linked video there is the ending song, though I'm not sure if the video is gonna be the video they use for the ending.
The second vid on the page is the opening sequence, and I know that for a fact that's the opening that is gonna be used when the showq hits the market on Sept. 18th.
The music, especially the opening, kicks ass... and isn't the smoothness of the animation just outrageous? It's beautiful!

Gary is happy.
