Lucasfilm and Twentieth Century Fox just announced the official release dates for the 3D editions of Star Wars Episodes II and III. Episode II will come out on September 20, 2013 and Episode III will come out the next month on October 11, 2013.
From the official announcement:
With its deeply detailed worlds and engulfing action, Star Wars is perfectly suited for the immersive 3D theatrical experience. Episode II and III deliver such captivating locales as the gleaming clone hatcheries of rain-swept Kamino, and the fiery lava planet of Mustafar as well as spectacular action sequences like Yoda’s unforgettable debut as a lightsaber duelist, the explosive space and ground battles of the Clone Wars, and the dramatic showdown between Obi-Wan Kenobi and Anakin Skywalker.
Supervised by Industrial Light & Magic, the meticulous 3D conversion was undertaken by Prime Focus, the global visual entertainment services company. With their proprietary View-D™ process, Prime Focus transformed Episode II and III into 3D with the utmost respect for the source material, and with a keen eye for both technological consideration and artistic intentions.
Episode I was released in 3D this past February. It brought in a reported $102.7 million.
