My understanding of the Electric Parade is all the floats were divvied up. WDW got some and the rest went to either Hong Kong or Tokyo. Never to return. I was only disappointed with the tribute to America float at WDW. The eagle looks smaller and the flag much shorter. But who really notices with all those beautiful women in red, white, and blue?
I heard they all went to Orlando as Tokyo has its own parade, the Disney Blog stated that it would be returning after they finish the DCA refurb which will be completed in the coming weeks. DCA needs it back to compliment the Pixar Play Parade or even better, move it across the esplanade back to Disneyland.
