Adrian Cockcroft updated his blog post, which inspired this TechCrunch article, and clarified that he was not in fact referring to HTML5 video, as the TechCrunch article (currently) states.

"MG Siegler at TechCrunch decided that I was talking about streaming video and Silverlight, which I wasn't. I was thinking of HTML5 features that let us build very cool user interfaces with drag-and-drop, canvas transforms etc. for the web site, and for embedded TV devices specifically."
