It’s very odd and sudden. Metro, the naming designation used for both Windows 8 and Windows Phone 7 products just got nicked. How so? It all seems apparently due to the random fact that a German company also has the same name — “Metro”. This could cause a potential lawsuit, so Microsoft has not only told developers to stop referring to the versions of their upcoming applications “Metro styled”, but also will be moving away from the name entirely.
As for a new name? The “transition from industry dialog to a broad consumer dialog” will introduce a new name (supposedly) to the design interface of Windows 8 and Windows Phone 7 to 8 devices.
