Although plans were underway for theatrical 3D re-releases of both Star Wars: Episode II - Attack of the Clones and Star Wars: Episode III - Revenge of the Sith, Deadline reports that Lucasfilm will instead concentrate their attention on the upcoming Episode VII instead.

It is unclear how much post-conversion work has already been accomplished on the two remaining prequels (Star Wars: Episode I - The Phantom Menance saw a 3D re-release last year), but it is possible that both films could find a theatrical re-release sometime in the future or that the 3D versions could be released directly to Blu-ray.

Plans also called for the eventual re-release of the original trilogy, although no release dates had been announced. Those plans, too, appear to be off the table for the time being.

UPDATE: Lucasfilm has now released the following official statement:

Lucasfilm has decided to postpone this fall's scheduled release of Star Wars Episodes II and III in 3D. Given the recent development that we are moving forward with a new Star Wars trilogy, we will now focus 100 percent of our efforts on Star Wars: Episode VII in order to ensure the best possible experience for our fans. We will post further information about our 3D release plans at a later date.
