Per THIS piece over at Deadline...
Paramount is moving the movie nine months to March 29, 2013, to add 3D. “We’re going to do a conscientious 3D job because we’ve seen how it can better box office internationally,” one of the studio execs just told me. “Jim Cameron did all of Titanic‘s 3D in post – and look how well that movie turned out.”
Also the execs say that the blockbuster performance of The Hunger Games shows that March can be a prime time of the year to release movies.
As someone who goes out of my way to AVOID seeing movies in distracting, eye straining, often inconsistent 3D...I can't say this news fills me with any level of awesome whatsoever. Perhaps this means Paul Fusco's ALF movie can be 3D, too. And cats can repeatedly run out of the screen to avoid becoming Gordon's dinner. Which, as much as I dislike 3D, might actually be kinda funny...
Thanks to @Robogeek for the heads up!
UPDATE: For those of you curious as to what might take G.I. JOE's slot on the summer slate, Universal has moved Seth MacFarlane's feature film directorial debut TED up from its July 13 release date to fill the June 29 void.
