Universal smartly wants its movies to be on the HD format that still exists, so it's switching to Blu-ray. If you would like to further delve into their rationale, here's their statement:
"While Universal values the close partnership we have shared with Toshiba, it is time to turn our focus to releasing new and catalog titles on Blu-ray," said Craig Kornblau, president of Universal Studios Home Entertainment.
"The path for widespread adoption of the next-generation platform has finally become clear. Universal will continue its aggressive efforts to broaden awareness for hi-def´s unparalleled offerings in interactivity and connectivity, at an increasingly affordable price. The emergence of a single, high-definition format is cause for consumers, as well as the entire entertainment industry, to celebrate."
