Looks like it's time Microsoft parted ways with Metro. No, not altogether, the new minimalistic design language will stay in the existing and future Microsoft products. The Redmond team is rather willing to change its name: officially, because Metro was just a codename, however, the more likely real reason is to avoid possible trademark law issues with Metro AG, a German wholesale company.
According to the official memoe by Microsoft, 'they are working on a replacement term', which has to appear 'by the end of this week'. As of today, the Microsoft employees are officially recommended to refer to Metro as 'Windows 8-style UI'. It sucks.
