Out of the blue Microsoft has rejected the "Metro" brand.
Just a couple of the articles covering this are from Microsoft Watch and Computeworld.
Here are some screenshots of microsoft.com references to Metro.
The statement released by Microsoft said:
"We have used Metro style as a code name during the product development cycle across many of our product lines," a spokeswoman said in an emailed statement. "As we get closer to launch and transition from industry dialog to a broad consumer dialog we will use our commercial names."And that is: Windows 8 Style?
