Dolby has announced that they will be developing a digital 3D system for movie theatres that will rival the current systems such as the Real D and In-Three systems.  See here . . .

Dolby has announced that they will be developing a digital 3-D system for movie theaters. The company has signed a deal with German company Infitec, a maker of virtual reality systems, to develop a 3-D system it hopes to debut in theaters by next spring. Dolby claims that it’s system will stand out above the other two technologies available today as it will not require either a silver screen (Real D) or battery-powered glasses (In-Three). Recently Monster House 3-D out-grossed it’s standard film release. The Hollywood studios believe that digital 3-D may be the future of cinema. I’ve seen all the 3D offerings so far and I tend to agree. I’m sure #d will be the future for animated releases, but am anxious to see how live action films will translate. Superman Returns 3-D was great, but they were only able to convert 20 minutes of the movie into 3D due to a tight post production process. It’ll be interesting once the technology process is sped up to allow same day and date releases.

Okay, we will see what we will see.  From the sounds of it the circularpolarization system being used for the current wave seem to be very good.  Hopefully, adding another system to the mix won’t screw up distribution.  Anachrome has a simple cheap system for film prints as well but it is not getting wide release as studios push digital and try to coopt the market in effect creating defacto monopolies as some films are not being shown in 3D in more than one system.
