An official statement from Lucasfilm informs readers that the planned re-releases of the Star Wars films in 3D have been postponed.  The posting specifically states Episodes II and III are the films being postponed with no mention of the films in the original trilogy.  With the statement that Lucasfilm will “focus 100 percent of our efforts on Star Wars: Episode VII,” it is entirely likely that the 3D re-releases of the original films has been altogether canceled.  Given that there has already been a lot of work done on converting the remaining prequel films to 3D, it’s a safe bet that, despite the delay, Attack of the Clones and Revenge of the Sith will make their ways back to the big screen.
