I'm not sure if I agree with the article.
Correct me if I'm wrong, but I can't help but believe I read somewhere that the adoption of the Blu Ray by consumers has been somewhat sluggish. If that's true, I can't help but believe the adoption of Ultra Blu Ray would be even more so. If so, is that due to Blu Ray fighting for relevancy against streaming or DLs?
Of course, you'd think the company responsible for the the format would want to push it. Additionally, do Ultra Blu Ray offer more space? If so, you'd think with games now needing to have a normal and pro mode now they'd want that extra space. Wasn't space an issue with certain games like The Last of Us and Uncharted?
