At the end of the teaser trailer it says Star Wars in coming in RealD and Imax3D.Cinderella wasn't coverted to 3D even for it's showings in China. I believe that this was intentional to gauge if no 3D would adversely effect box office. I'm sure to the joy of some 3D hater at Disney Cinderella did great worldwide with out 3D, even in China, and I suspect this will be used to end production of 3D live action features at Disney. Having ended release of blu ray 3D disc production in North America I think we will see an end to feature production too. It remains to be seen if they will continue to release animated pictures in 3D and the 3D decision making has been left up to the Star Wars and Marvel brands as to 3D release. My bet is Star Wars will will be released flat in the USA and released 3D in Asia. This will test my powers of prognostication.
