To hear Sony tell it, the future will be in 4K. This stance comes as no surprise: The company’s 4K-rez digital cinema projectors have been installed in over 13,000 theaters, and at least 75 Sony-produced titles have either been shot with 4K digital cameras, or transferred to the higher-rez format from film. And Sony isn’t just pushing 4K for theaters — it wants viewers to experience it at home.
