The horizon for Blu-ray Discs is as clear and blue as Dr. Manhattan, according to sales information just reported in Home Media Magazine. The report shows that 36 percent of all disc sales of Warner Bros.’s Watchmen were on BD, which is a new record for the high-definition format. Quantum of Solace, the previous Blu-ray champion, captured 28 percent of all disc sales when it was released back in March, while Iron Man got 17 percent. Blu-ray Bob predicts that we’ll see a 50 percent Blu-ray sales record by the end of 2009. If he were a betting man, he would place good money on it being either Star Trek or The Lord of the Rings: The Motion Picture Trilogy. You heard it here first.
