I remember reading back in March on the oc register this:

The classic Electrical Parade at Disneyland is on its way back, this time to Disney’s California Adventure. Disney spokesman John McClintock said the seasonal night parade — marked by float’s and characters decked in thousands of lights — will start again in June.
There will also be a number of other new after-dark shows and attractions — possible a new fireworks show.
McClintock said all of the details of these new shows and features will be announced April 24 — a press event that we at Around Disney will, of course, be folllowing.
