I've just been watching a video with Alain Derobe who is arguing that 3D lacks of standardization and this would need a visionary man to push the industry.
Like Estman in 1910 who travelled the world to put 35mm print as a standard, there should be a man that could convince the industries for the good of 3D beyond DCI.
He speaks about the unaxeptable light loss of current 3D projectors/systems.
Listen to Alain Derobe
The whole interview is very interesting but he speaks about this particular point @ 11'00''.
PS: We all know a man who could do this... ;-)
