As stated on the Official Site:
Lucasfilm Ltd. and Twentieth Century Fox announced today that the 3D theatrical launch of Star Wars: Episode I The Phantom Menace now has an official release date -- February 10, 2012! Set against the thrilling and exotic backdrop of a "galaxy far, far away," Star Wars is perfectly suited to the immersive 3D theatrical experience, and Episode I delivers some of the Saga's most stunning and spectacular sequences -- from the Naboo invasion to the Tatooine Podraces to the climactic lightsaber battle between Darth Maul and the Jedi.
Supervised by Industrial Light & Magic, the meticulous conversion is being done with utmost respect for the source material, and with a keen eye for both technological considerations and artistic intentions.
So February 10 - right in the middle of winter, so hopefully it will do well with the lack of competition. Less than a year; that's pretty sweet!
