Roger Ebert recently commented in his "Movie Answer Man" column about the future of the digital cinema standard which has  been gaining support from many of Hollywood's large studios. When asked about how he thought the new format would affect the future of the cinema, he stated that he had a few reservations.

Still uncertain is: (1) Who will pay for the still-expensive projectors? (2) Will widespread digital distribution be an invitation to piracy? (3) How will the public react to buying tickets to moves they can essentially see at home at about the same projection quality?

He goes on to talk about an alternative to digital projection called Maxivision which projects the movie at 48 frames per second and has superior quality compared to standard projection. The Q and A column on the site is a good read and gives an insight into some of Ebert's views, look for the specific question on digital projection second to the bottom.
