Cinema industry will continue to develop intensively and extensively. By 2020-2030 3D format will finally prevail. Internet will entice big part of the audience of cinema theaters, China will become a big player on the Global market, Europe will remain the center for art-house. Basics of cinema language will remain the same.
The prediction for the next 100 years seems to be just a very modest prediction of the current trends, it doesn't foresee any significant changes that of course could happen in a century.
