According to the LA Times Travel Blog:
While the OMG web rumors aren’t true, the new Maleficent dragon won’t make her scheduled debut this weekend at Disneyland in the upgraded Fantasmic show due to “technical issues.”
Disneyland officials say those “technical issues” do NOT include the latest Internet rumor du jour pinging around the Twittersphere — that the 40-foot-tall dragon’s neck snapped during testing and that the head fell off!
The show will go on sans the dragon — with the new Fantasmic making its official debut on Friday (June 12) with the new Flotsam and Jetsam eels and high-definition video projections on the mist screens.
The new dragon won’t join the show until “later this summer,” according to Disneyland officials. That likely translates to a delay of weeks rather than days for the iconic image of the Anaheim theme park’s Summer Nightastic marketing push.
