De acordo com o wiki do Logos ,
In 2006, Walt Disney Pictures started using a new intro with a new CGI animation with a very complex depiction of the Sleepy Beauty Castle and its surroundings. It was a clear change from the old blue and white intro with its stylized castle and 2D animation.
The new intro was first used on Pirates of the Caribbean: Dead Man's Chest, which premiered in the United States on July 7, 2006.
Starting with The Muppets, "WALT" and "PICTURES" have been removed from the logo.
2006 é o ano em que a Disney recomprou a Pixar e no ano seguinte a Robert Iger assumiu a Disney. Há um lançamento da Pixar Disney, mas, estranhamente, essa nova introdução não foi criada pelos estúdios Disney, mas pela Weta Digital na Nova Zelândia.

On a night sky background, we see a star, a la Pinocchio. Then, some clouds appear, a la Mary Poppins, and a pirate ship, a la Peter Pan. We then see the castle, done in CGI, while different fireworks are appearing. A circular line is drawn over the castle (in the same vein as the previous logo), then the castle enters many dots from the bottom of the screen to reveal "Walt Disney", in the post-1979 Disney script logo font, albeit slightly revised. "PICTURES" fades in, while the circular line is nearly staying visible on the logo.
O trem pode fazer referência a Dumbo , mas não encontrei a confirmação disso .
