It’s official, Warner Brothers, one of the early backers of HD-DVD will release movies on Blu-ray as well. This leaves only Universal as the only HD-DVD supporting studio to commit to Blu-ray officially. None of the Blu-ray studios have yet said they will support HD-DVD, which means that, assuming Universal switches to support both, as they are expected to do, that all the movies you could want will be available on Blu-ray, while far less will be available on HD-DVD. Now if we could just get the big retailers to commit to Blu-ray alone. Say Best Buy, Wal-Mart and the like come out and say “we’ll only sell Blu-ray” devices and content. We will not sell HD-DVD devices or content.” The retailers could finish this format war off right now.
