Microsoft's 'Metro' Is No More, It's Windows 8 UI [zdnet.com] Here's the official guidance, my sources say: Anything currently/formerly known as a "Metro-Style application" (with or without a hyphen) will now be known officially as a "Windows 8 application." References to the "Metro user interface" will now be replaced by "Windows 8 user interface." And instead of saying "Metro design," the Softies and those adhering to their official guidelines will be using the words "Windows 8 design."
