Here's the official guidance: 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."

Update: According to The Verge, Microsoft is now calling it Modern UI Style. An MSDN blog post, made available this week, also references "Modern UI design." An internal memo revealed that the company was planning to select its Metro branding replacement last week, but the company has not yet officially named the replacement.
So please remove "It's Official" from the topic title.
