Although, to be fair, it must be noted that HD DVD version of The Departed is a HD DVD/SD DVD combo disc and so costs $5 more than the Blu-ray version. Sony VP Rich Marty said that he expects the gap between Blu-ray and HD DVD to further widen with the Sony title, Casino Royal, headed for Blu-ray and (of course) not HD DVD. However, Universal VP Ken Graffeo warned against drawing conclusions from these figures.
"You can’t look at the last two months as a trend or as what the consumer wants to do in this format... It’s really an artificial, short time period," he said. He also suggested that there are other reasons for Blu-ray's boost in sales, including two-for-one offers made by retailers, and Amazon's 50% reduction on selected Blu-ray titles.
