Release year is conservative because LG's Australian launch table schedules 55″ and 65″ for March and 77″ for April, while the surrounding text says the range starts in April. The US schedule gives April for 55″ and 65″ and May for 77″; these schedules do not establish a single actual first shipping day.–
